    I’ve never built anything with an Arduino, but I really would like to. I have a little boy and I’m a single mom. I think it would be awesome for us to build something together and let his creativity be our guide. :) He loves music and things that light up, soooooo, this might be the perfect gift for us. :)

    How do you choose a single project when this kit gives you SO many possibilities ?!?!?!

  4. Paul Tate says:

    I have not built anything with arduino yet, but I would like to incorporate one into an RFI kit for the front door of my house. That way I can give out RFI keys to the people I want access and be able to control when then can get in.

  5. Greg Swan says:

    After reading this month’s WIRED all about arduino maker projects, I’m super psyched to build my first project. I’m thinking specifically about ways to leverage online behavior (e.g., tweets) to mechanical action (e.g., lights/sounds). Pick me!

      ‘reverse geocache’ as in…
      what, you hide and a little geocache comes and finds you?

      1. Ethan Dicks says:

        A reverse geocache is a locked box with an Arduino and a GPS that opens when you bring it to the correct location (i.e., you wander around with it and triangulate the opening spot based on what it is telling you on its LCD window).

    I haven’t done anything with a microcontroller, but I think I would like to build something for the Cub Scout troop. They already have a device to measure the pine wood car derby, but they don’t have anything for the rocket derby. Currently they have dad’s stand around with stop watches to time from start to finish, if they don’t finish, they measure how far they went (they are rubber band powered and hang from a string). I think I can change the line to a wire and the hanger to a carbon pad and measure the distance by sending a signal down the wire and measure the time it takes to get a reflection back. Timing should be easy in that I just have to have a switch at the other end to stop the timer or I can still use my reflector and that way they can have the stopping point varied. I think the hard part would be figuring the freq to use for the pulse what to expect back. It will take some testing, but I have some scouts that would love it.

    BEST THING BUILT: Automatic fading night light. An IR motion sensor and three white LEDs hooked up on an Arduino NG. I built it when my son was born so we could see to do baby maintenance at night without turning the room light on. It fades up fairly quickly when it sees movement and fades down over about 3 minutes when there’s no movement – leaving everyone to sleep in a nice dark room. That was almost 4 years ago and it’s still going strong! Wouldn’t be without it.

    DREAM BUILD: Arduino video motion-control rig. I’ve actually been working on it (on and off) for a few years but I really want to push it forward to being a solid piece of useable kit.

  15. Jason Trotter says:

    Last little robotic thingy I made was in school, a little robot that would follow a white line, record it’s speed and distance traveled. I think I want to somehow use this to record how long it’ll take my hedgehog, Prickles, to get to the moon on his little wheel.

  18. Jeff Murry says:

    The cooles microcontroller project I’ve ever built is my Mouse trap Alert. I have had an ongoing issue with mice in my crawlspace. Trapping them got a little easier when I found a battery powered electricution type trap, but it was still a pain to constantly check into the crawlspace all year long. I developer a combination of wireless radios with microcontrollers and LCD displays to send a signal from the trap when it traps a mouse (or runs out of battery) to a receiver that sits on my desktop. Then I only check the trap when there is an actual catch or low battery.

  23. Peter Young says:

    The coolest microcontroller project I want to build is an RF remote control for Lego trains that has a hand held controller run from an Arduino, LCD, buttons and an XBee which communicates with a Xbee and arduino in the trains to control them but also communicates with track side accessories like signals and switching points so that they work together to simulate a real train operation. So far I have some basic plans and circuit diagrams for it all but an lacking anything to prototype it with.

  24. John Thomas says:

    I haven’t built anything yet, I am just getting into Arduino. I want to build a Moog style synthesizer. That would be the dream, actually, I want to build an army of different synths that can play together. I also want to start teaching my children about electronics so they can build cool things.

    I always leave the garage door open so I recently built a garage door sensor with an arduino and ethernet shield. It uses a reed switch to determine if the garage door is open and it sends my wife and I a text message if it is open after 8PM. I also hooked it into the garage door opener so I can reply via text message to actually close the garage door. I can also query the current status (open or closed) via text message. It’s been working great and saved my butt a few times.

    The coolest thing I have ever made was the humble “metrognome” but on a breadboard. It was two weeks ago and my first project. I wanted to play around with the source code and see what I could learn.
    It raised question about clock speeds (the arduino seemed to run about 50 times faster than the atmega on the metrognome for example).
    I had to learn a bit about crystals and how they even work (though I didn’t have to use them).
    In playing with the confused speeds I got to understand the what the seven segment displays work (I didn’t realise it was to do with strobing or whatever the term is.
    I learnt to read the product description and datasheets/comments on the product page, because I was convinced there was a way to use what turned out to be an unwired led.
    I learnt breadboards run out of space really quickly (and recently found out about Fritzing, which is just rude sounding).
    Basically it was a cool project because it was my first hardware programming experience, and I learnt an insane amount in a short time.

  31. Jess Hires says:

    The coolest microcontroller project I’ve built was an NES controller interface. It was really neat to learn about the builtin shift register in the NES controller, and how to read 2 controllers at the same time. I plan on porting it to AVR from the Arduino, and have it read as a USB gamepad HID. I would feel amazing if I could somehow get it to work with the zapper, too! :)

  32. Colin says:

    I am working on a single-arm barn door tracker for astrophotography, driving the tangent arm with a stepper motor and adjusting the drive rate to compensate for tangent error. The whole idea is to track the stars across the sky for long exposures.

    However, in the middle of building that, my company had an RC car race… One of the prizes was for best obstacle. What I love about the arduino platform is that I was able to use it to make a moving-ramp trap based on the work I had done to drive the stepper motor in an afternoon – won the prize! I think the best part was when I watched one driver waiting on the ramp for it to move into position got rear-ended and dropped off the end of the ramp by the next driver, who in turn was able to get past the obstacle first.

    I’ve not built anything yet but I always go hard which is why I’ve started on a reprap and a desktop cnc

  38. Will Austin says:

    I’ve only just gotten started with Arduino. I picked up a handful of projection displays (used in instrumentation before VFDs and LEDs became popular) and had most of it built and working using TTL ICs. Each display has 12 possible digits to project, so it’s almost like a nixie clock circuit. I’m trying to convert the project to Arduino and dip my toes in programming.

  39. JR Lewis says:

    Created a light-up Bustier for a community theater show. The actress could use pressure sensitive sensors inside the tips of her glove thumbs to control which sets of LED’s lit up and how bright. Press both down really hard to set off an animated pattern of heart shaped groups of colored LED’s. Built for the song ‘Gotta Have a Gimmick’ for the review ‘And the World Goes Round’. Arduino, flexiforce sensors, Lots of LED’s, and some lingerie.

  40. Addidis says:

    Ive been building an electronic control unit for my RC truck. The engines in RC cars have fuel adjustment needles. So you need to trim the fuel (which contains the lubricant) depending on the weather, humidity , and performance you desire. Less fuel = more power = less lube and engine life. By logging the temperature of the engine head and connecting the fuel screw to a servo I am going to try to make a PID controller to automate the tuning. So far im building it from what I have laying around. It would speed up development to use the arduino libs. This project , and source code for the datalogger portion nearly done is posted at jeselectronics dot com currently using PIC. Its titled RCecu there are a few posts on it.

  41. Simon Thomas says:

    For a university project, I built a Jukebox that played polyphonic “songs” through a small 8 ohm speaker (through a SPI interfaced DAC). It was powered by an Atmel ARM7 AT91SAM and responded to inputs from an alphanumeric keypad. It also drove a small display to inform the user of the track number and current play time.

    A coworker had to retire from networking due to sensitivity to EMF, so of course I built an EMF detector, mostly from Collin’s design, but I did manage to fit it into a Trader Joe’s chocolate tin, with the bargraph in the clear plastic center window. I even used a circular perfboard. He was blown away at the retirement party that it actually worked. I was blown away how much EMF our Motorola radios emit while transmitting, good thing we don’t use them much…

    It’s time to put my greenhouse to work, and not as a storage shed. My goal is to get temperature humidity, illumination and soil moisture sensors hooked up to the Arduino, then communicate this to my PC inside. Then, I’ll look into controls for automatic watering, supplemental lighting and maybe a cooler or fan.

  47. Sean Farquharson says:

    I am using a hydraulic motorcycle scissor lift I picked up on ebay to lift my video projector out of a piece of furniture when I want to watch a movie, the only annoying part is that my Harmony remote will set everything up for “movie time” with the touch of a button, but then I still have to get up and physically step on the lifts foot peddle to lift the projector up and put it away. I want to use the ardunio (along with a shield to isolate the 120V current ) to detect when the projector turns on an off (either using the 5V switch output on the projector, or by use of a SmartStrip power strip) and raise and lower the projector (by the correct amounts) as needed. There will also be senors to stop the lift at the right hieght and when the cabinet is fully closed.

    I’ve designed a Calorie Tracker Module that counts the number of calories I have burned over the course of a day. It constantly measures my heart rate, body temperature, movements, gait, and other physical variables to estimate the number of calories spent. It can tweet my body state and predict what exercises and activities are best for burning calories.

    A garage exhaust system. Two Picaxes: one measures inputs, including indoor and outdoor temperature and presense of Carbon Monoxide. Servos are used to control fan direction. The other Picaxe is a User Interface connected to a 2 line LCD display which shows the temperatures and fan and CO status.

  56. Gregg says:

    Coolest?! I’ve gotten an example from the Arduino site to work for showing numbers on a serially enabled LCD display to work at least twice. And surprised the person I was showing it to.

    Dream project?! On the Pachube site, it describes one connected via Ethernet, and doing “something”. Does the kit contain a basic Ethernet shield? That’s what I need. People have also gotten exciting response from a tethered one, and it needs the parts described. Okay that may not be a winner one, but that’s my dream.

  57. Tristan John Cannon says:

    I have made a usb microcontroller interface which has 8 digital inputs and outputs and 1 analogue input and output. Unfortunatly it uses C++ to program it. Ive seen other kits available in America, such as Basic stamp, but alas, in England we dont have an innovation culture and these products are unavailable here.
    My original project was an automated vacuum cleaner, which would work if the microcontroller used a language that I understood. I managed to download the software for basic stamp and PCB design software which includes a BS module, i used this to play around and see my project working vertually, but since the actual BS is unavailable here, never got to finish it. I have a prototype built, its just waiting to recieve a microcontroller.
    My ultimate project would be to wire EVERY electrical appliance (including clocks) in my home to a microcontroller and with the use of my pda or a computer connected to the internet, be able to control everything in my home, from anywhere in the world. Ive designed a lighting system which uses different coloured LEDs, which would be part of this intergrated system. The purpose of it is to give blue light in the morning and red light at night. i got this idea after reading that when blue light contacts the retina, the brain produces seritonin and red light produces melatonin. The morning light would help me wake up, and the night light wont wake me fully when i go toilet at night. Also, with the system linked with fire/smoke detectors, the lights would come on blue at night, they could also be programmed to show safe routes out of a building.I even dont see much of a challange in making things to help with chores around the house and linking it all in together. Electric water valves could mean even my bath can be controlled. i could have a freshly run bath waiting for me when i wake up in the morning.
    With additional software like dragon naturally speaking, i could have this entire system voice controlled.
    “computer, I would like a cup of coffee while I watch stargate and this floor could do with a hoover. oh and i wish to have a bath ready for 2100h.”

    I dont see why everyone cant have a house of the future, it doesnt have to cost millions.

      don’t go the basic stamp – I got one here in australia and had to go through getting a USB-serial adapter (I use mac) and BASIC is a terrible language – and then after uploading the first program, it works, but, alas, no program afterwards has ever uploaded. and believe me, i’ve tried. i guess it’ll have to stay with a !@#$%^& blinking LED for the rest of time…

    I want to integrate an RFID reader into my dog’s door to permit my dogs (RFID attached to collar) to automatically gain entry into the house based on their ID and/or time of day. I’ve already built the web service and iPhone app to monitor my backyard. One important feature would to be to set an exception (remotely) for a rainy day and sound an alarm to let them know they’re able to enter the house. The web service and mobile app have already been developed, I just need to get my hands on an Arduino.

    I think the coolest project I want to build is an improved thermostat for my house. I always thought it was silly that you can set it to cool or heat, but not both. I want a range. If it is less than that, I want it to heat up, if it is more than that, cool it down. Ideally, being able to eventually hook it up to a wireless network so I can open/close vents would be also useful, that way I could get a more even temperature or handle the fact my living room is always a few degrees colder than the bedroom. I’d want to build it so it can be a bit more intelligent about the weather, so if it knows it is going to be cold, it can start heating up a little earlier.

    My arduino is my prototyping platform before things get moved onto (usually) smaller AVR chips. In the past, the coolest thing I’ve made is an RFID authorization system (scan a tag, and it’ll enable an output or not, depending on if your tag is in the authorized list). Right now, it’s being used as a logic analyzer to reverse-engineer a motorized tripod’s serial communications. Soon (I hope) this tripod will be controlled by the arduino!

    As an 15-year old maker I’ve always wanted an arduino to play with, I recently got my first Breadboard from RadioShack along with the 555-timer chip. Breadboards are awesome, and that someone thought of combining the arduino microcontroller with a breadboard and fit it in such a small design as the protoshield is even more awsome. I’ve always wanted to make a homemade alarm system, with maybe 2 sensors, for my room or my candy drawer, i already have the magnetic switches ready here on my project desk, people are always stealing stuff from poor makers like me, hehe. Having an arduino, and even better the starter pack, will finally get me going on building my basic alarm system.

    A combination Color-Button Door lock with Net-connectivity. We will be building a net-zero home and I would love to make a door lock that the code is a 4 color sequence. The keypad would have 4 buttons that change each time you press a button. So the COLOR sequence would be the same but the location of the button would changer each time.
    Also it could be web enabled to be able to text server or click a button on a url to remotely open the door. This would be instead of giving someone the color combination or a key. “Just call me when you get there. I’ll let you in.” 8p

    I dream of building a MIDI keyboard controller with a ribbon controller as wide as the keyboard (in tribute to the CS-80) and four ribbon controllers to the left of the keyboard for controlling various parameters. The ribbon controllers will have rows of LEDs behind them that will light up so the performer can keep track of what value the parameters controlled are at. The keyboard will use piezoelectric sensors for velocity and pressure sensitivity. It will be semi-weighted, since I find fully weighted keyboards to be overweighted.

    I’m working on a ‘perimeter chime’, basically it’s a wireless tripwire that uses the unique properties of vinyl fencing (meaning, that it’s rather flimsy) to detect when cats or small animals jump on or over it. The vibrations created by normal wind are different, so I’m able to filter those out. The tripwire increments a counter (I’m hoping to timestamp it in the future) so I can see which time of day the vagrant cats are more active in my property probably scoping out my chickens or pooping in my corn patch.

  84. Fox Slawnych says:

    Last year, when I was in grade six, for a geography project we had to design and make a product and find out about what raw materials that we would need. I decided to make a vacuum-bot, with two cds cells and a spring coiled around some bare wire for sensors, an Arduino for a brain, two motors, and a dust buster. I couldn’t find any code for any projects like this one, so I made some from scratch. While the other kids where making products such as night lights and necklaces, I felt really smart making a robot that actually worked. Thanks to Arduino, I got a robot that vacuums, and an A+!

    I’m aiming to use several microcontrollers in my new boat…
    to interface many sensors (inc accellerometers, electronic compasses and environmental monitoring), to control several solar trackers, to control appliances through an onboard computer and to control some slave panels to allow basic functions to be accessed without needing a full computer…

    I hopefully will be starting construction in the next month or so… for the boat I think I will have by the autumn….

    I have built a dog tracking device for our my new rescue dog, it uses an RFID reader mounted in the door ways, connected to a x-bee module. It logs when the dog is walking around the house, and eating(one RFID reader mounted near the bowl). We also put a chip inside one of the toys to see when she picks it up. She has an RFID chip on her collar to track her. This allows us to make sure she is eating and exploring her new home.

    Have been of getting the arduino for some time but have not gotten around to do it yet. It may not very sophisticated but i wanted to build a robot with stereo vision to detect object and move around them. Eventually add log shield to map the area which the robot has already visited. Just something I have been think about.

    A friend of mine and I are building a fully automated Golf Ball Gun. It runs on oxy acetylene and oxygen. We are using the arduino to run the entire thing. What happens is first the arduino triggers a linear actuator to load a golf ball. Next it triggers servos which open valves to let in the oxy acetylene and oxygen into the measuring chamber which, as you guessed, measures the amount of gas. The measuring chamber is also powered by arduino. It then dumps the gas from the measuring chamber to the guns chamber, then activates a servo to press the button on a stun gun to ignite the gas. I know what your thinking, “how are they going to power all this with an arduino?” So we designed a shield to up convert the power from the arduino without any compromise. In a nutshell, with the push of one button, the arduino will measure the gas, dump it into the chamber, load the golf ball, then fire it. I figured all of this out, and I am 14 years old, so as you can imagine moneys tight. I can’t exactly build any of the circuit without the kit, surprisingly it has everything I need. I can build the gun out of scrap parts but I cannot build the circuit with out this kit. As you can tell I am smart enough to handle the arduino but can’t if I don’t have it. I have been wanting it for quite some time but sadly cannot get it because I don’t have the money. I know how to program the arduino but I never actually seen one in person so having this would be absolutely wonderful. My dad just got me my first ever Make Magazine, the arduino revolution and I am learning as much as I can, but again cannot use these skills without it. So please, PLEASE send me this kit. Words cannot express how grateful I would be.

    The Minimalist Oscilloscope 08M Project

    One day while doing some research on something or another on the Web, I came across a link explaining how to connect a MicroChip PIC to a Nokia Cell Phone LCD Screen. Sounded cool; I had been playing with PIC’s and PicAxe’s anyway and thought it was knowledge that would be useful someday. Then I found a Nokia 5165 Cell Phone at an Electronics Flea Market ( for $1.00, and at that price, I couldn’t pass it up! I knew I could hook the LCD up, but wasn’t exactly sure what I was going to do with it, when one day it struck me… PIC’s have an Analog Input (ADC) – I could make a very simple, little Oscilloscope! A “Minimalist Oscilloscope” – and thus The Minimalist Oscilloscope 08M Project was born.

    Doing more research on the particular model of Nokia Phone I had (5165); I found this page ( with a very similar model showing how to connect it up. I knew that soldering 0.05 inch pads and components (Surface Mount size) is very difficult from previous bad experiences, so I decide to use individual strands from 22 gauge stranded wire running from the circuit board pads to a 0.1 inch socket I had cut in half and epoxyed in place. Soldering was very frustrating; several times, while soldering one pad, I’d mess up the one next to it and have to redo it (one-step forward, one-step back.) Finally got everything soldered in place. That was with out a doubt the hardest part of the entire project!

    After the most difficult part was over (soldering surface mount wires), the rest was fairly easy. I built a simple circuit on an experimenter’s breadboard, and made a simple program to test that I was interfacing to the LCD properly (amazingly, it worked first time!)

    I built up the code until I had a system that would…
    1. Wait for a Trigger at half the peak to peak of the signal on the rising-edge (Yes; it is a TRIGGERED Scope!), with a time out for when there is no signal
    2. Take 42 measurements of the signal as fast as it can and store them in an array.
    3. Display the measurements on the LCD Screen.

    Yes; it really does work!
    Check out these impressive specifications rivaling scopes costing twice the price (about $9 MSRP)…

    * Vertical fixed at 5V full screen (or 0.5V per division, if it had divisions.)
    * Horizontal Sweep fixed at (approximately) 43mS full screen when over-clocked at 8MHz (or 4.3mS per imaginary division.)
    * Trigger fixed at 1/2 the peak-to-peak signal (with a time-out when there is no signal.)
    * Non-portable (unless you want to carry my entire workbench some place.)
    * Very Affordable (about $4.50; $3.50 for the PicAxe, $1.00 for the phone, everything else I had on hand.)
    * Visible in Day Light (the LCD Backlight is not connected.)
    * All Solid-State (using ultra-reliable E-Z Clip Technology.)

    I have built, and am in the process of improving, a time-lapse camera stand, using microcontrollers to both operate a camera motion system, and monitor and maintain soil moisture levels.

    The first version of the motor controller used an old microcontroller module that I had in the junkbox, but its functionality is somewhat limited. It worked for a “proof of concept” sort of build, and I’m happy with the first-run time-lapse shots, but it needs to be improved for the next version. The controller monitors the camera’s activity, and advances a motor a set amount, in order to move the camera carriage incrementally between shots. I hope to use an Arduino board for the new version, as it has far more program capacity and I/O capabilities than the micro that the first prototype was based on.

    The automatic watering system is based on an Arduino Diecimila unit. After some early difficulties with the soil moisture probe – the copper was completely eroded away due to electro-chemical reactions – I have a new version that seems to be working fine. It reads the soil moisture levels periodically, and when necessary activates a home-made metering pump that I constructed from junkbox parts, fish tank fittings, and an animal nursing syringe, to maintain the soil at just the right moisture level and keep the plants happy.

    So far, everything’s been working well, and most importantly, I’m learning a lot and having a blast.

    I built an interface to control all my modifications I’ve done to my Commodore 128D. It uses a mega32, 40×2 char LCD, a couple of buttons, and couple of max 4066 switch chips. With the LCD and buttons I can cycle through the options and the built in nvram in the mega stores them. I put the outputs of the mega to the 4066 chips. Those chips are wired to the various mods. I can toggle the address lines on the multi-banked kernel eeproms to swap the kernels for 64 or 128 mode as well as the built in 1571. Like jiffydos, dolphindos, speeddos etc. I also have several custom autostarting function roms for 128 mode that are banked into a eeprom selectable from the LCD interface. There’s a few other odds and ends I added too like being able to toggle a couple of lines on the cartridge port, and the ability to reset the machine via the front panel.

    I’m pretty sure there’s enough room left in the mega to add a track/sector/density display to the LCD for the built in 1571 drive as well as being able to control the write protect on the drive electronically instead of on the floppy itself. I’d use the arduino to do some more development on the ModCom128 as well as other projects. I’m planning on moving my 128 into a tower at some point too. My current dev setup is nothing more than a breadboard, a wallwart, and an old serial AVRISP heh

    I built a little arduino project once that read my email inbox and lit an LED coded to correspond to the appropriate “danger” level of my unread mails. E.g. if they were mainly work-related and from people I disliked, the LED blinked red, while emails from people I love or with good keywords made it shade towards green. It led to epic procrastination whenever the light shone amber through to red, though…

    Back in college I built an NTSC video generator and had 36 hours to do it. We had walked out on the first test in the class when the professor was an hour late, and he was stubborn, so we had to make up for it in a final weekend project. Bonus points for something tricky. Come to find out, analog video is pretty tricky to generate from scratch – figuring out output voltages, working out the timings, pseudocoding (for the first time ever in a project :) building out the board and… 36 hours later when I flashed my Arduino it worked right off the bat and I sat staring at the alphabet being displayed by this little protoboard on the TV for an hour. Felt great. Still got stuck with an A- from that guy… lots of others did egg timers, he did animated NTSC as “his” project (it was pretty slick). 5 years later and I’ve been recommending Arduinos to friends ever since who are all doing really neat projects (they’ll be along to comment shortly).

    I dream of building a salt water reef heaven, for many kinds of corals and fish. It will include pumps controlled by a microcontroller to simulate waves. Not only that but it will have an array of leds lighting the tank. The microcontroller will control each individual led to simulate day, night, dawn, and dusk lighting patterns. It will also control a moonlight which will follow the real time moon cycle. I would like to program to controller to simulate cloudy days and clouds passing by, and full blown simulated thunderstorms with intensified wave patterns produced by the power heads. This is only the beginning!! There will be an automated feeding system, along with automated water changes, automated dosing of trace elements. Also temperature, ph, and salinity control through various probes attached to the microcontroller. The list goes on, the possibilities are endless!! Making this dream into a reality would be priceless!! =D

    My son and I just started building Arduino projects, after the great tutorials in Make Magazine. We built a Ping Pong Ball Cannon which we demonstrated at his school yesterday. It uses the Make Compressed Air Rocket system to launch a ping pong ball from a tube. The angle of launch is automatically set by an Arduino, which measures the target distance (a plastic bin) with a PING sensor. It then solves the parabolic trajectory equation, sets the launch angle with a servo, and fires the cannon with a reed relay circuit. We had a great time – the 5th grade kids learned about a simple physics equation, and discovered that math is cool and fun. Now my son and I are both competing for our Arduino kit! We want to build more educational projects, and could use another. Thanks Make for introducing us (and a class of 5th graders) to the capabilities of Arduino. You’ve opened up a fun new world.

    A project I’ve wanted to do is to combine an infrared thermometer with a mechanical television setup to build an improved thermal imaging camera. The way the mechanical television works is that a motor spins a disk with a pattern of holes in it so that the sensor array is exposed one pixel at a time to the the subject.
    The array in a mechanical tv is just a bunch of photo-resistors that measure the intensity of the light and record it for playback. I want to replace the photo-resistor with the sensor from a hand-held infrared thermometer.
    For playback i would either have the arduino store the images or stream them directly to the pc where a processing sketch could be used to display the video.

    Some challenges for this project would be controlling a large spinning disk to keep it at a constant velocity so the image remains stable. That would require a simple PID algorithm which the arduino could handle easily. Storing the image might require an sd card shield to store more than a few frames at a time. Another option for this would be external eeprom. The slow refresh rates of the IR sensor may require the frame rate to be dropped from a standard mechanical television or to lower the resolution. Mech TV was usually maximum 320×240 but I could lower that by 2 maybe and still get an image that is recognizable.

    My Arduino project idea is to build a device that turns on the kitchen faucet when my cat, Thomasina, wants a drink. Now when she wants water, she jumps up on the counter and alternately meows, looks at the faucet,then at me until I turn on the tap. The Arduino will use a sensor (touch, or motion) to actuate a solenoid that will turn on the flow of water. The Arduino will allow me to program in a delay to allow Thomasina to have a long drink before shutting off. The device will save water since I now sometimes forget to turn off the water. I can expand the project by calculating the flow of water and the time that the faucet is on so I can find out how much Thomasina is drinking, which is a good way to monitor her kidneys. The device can also be used to allow me to turn on the water when my hands are dirty. I’ve seen many interesting projects, so I’m sure that to decide who gets the kit will be a tough decision. Thanks for the opportunity.

    This is still a nascent idea, but being a car enthusiast / programmer, and a big fan of all things open source, I’d really like to build an open-source ecu around something resembling an arduino, a cheap, freely available microcontroller that could easily be modified to run on various engine types and to control different engine components. It would just be really excellent to offer something like this to the automotive community. Imagine being able to interface with your ecu in real time without really expensive software! Just grow your own ECU readout/command GUI and get it to interface with the arduino. Snap. GTRs for the rest of us :p

The environmental part comes in by teaching the local community about how they can save power and be tech-savvy, such as helping white-wash roof tops, building heaters for during the winter out of recycled window frames, tin cans, and a dryer tubes. We wish to build cheap solar panels and use Arduino’s to regulate them, and give them back to the community.

You will have a second option to let fall a second drop, within the time you want, so you can capture that splash effect of 2 drops splashing each other.

    I would like to have some sort of people detector ranging from something simple (it is a single couple nearby or it is very crowded?) to a full blown kinect sensor for that purpose. This device would then do simple music analysis as for example, is it rhythmic or mostly slower and melodic? it would then adapt lights and music volume (maybe some EQ/FX in the future?) according to music type and the nearby audience! This could start from something really simple to more complex stuff as analyzing dancers’ movement and adapting light dynamics to sharp movements of the dancers or the music or weighting both inputs to act upon lights and music. The options are endless! :-)

In addition to the RGB LED, there was an IR emitter and an IR detector by the “mouth”. I taught a workshop where the students each built one “sheep”, then we loaded a basic sketch onto it that pulsed IR out and “listened” for IR in – if the sheep didn’t see enough pulses, they got “lonely” and their LED turned Blue. Too many pulses, and they got “angry” and their LED turned Red. Just enough pulses and the LED turned Green.

    I would really like to build a robot that is controlled by my brain. Using Some EEG device (like that starwars force trainer)

    I also had an idea for a great april fools day prank… it would be an Arduino mounted in my top-opening mailbox with a motion detector. it would have audio with it and a servo. So when the mail man came up on the porch the mail box would pop open and closed like a puppet mouth and talk to him.

    I’ve done a single project on college with Arduino. It was a Plant Care system (similar to Garduino) which was controlled by a DECT phone (that part was done by my friend).

    It got me very interested so I would like to do some more projects or even give at away as a present since I don’t have much time right now (for next few months).

  347. Matt says:

    Alright…maybe it isn’t the coolest ever. But I have a pretty important application for the kit I plan on building.

    I just moved into an apartment building. Their policy is “we don’t have a key to your deadbolt. So if you need maintenance you need to unlock it the whole day while you’re at work, or you need to be present to let us in.”

    Obviously I don’t like the idea of leaving my door unlocked all day long. So I REALLY want to make a remote controlled door unlocker for my deadbolt. I need a mechanism for turning/opening the lock, another for wireless communications between the Arduino and a PC, and an Android phone to communicate with the Arduino via the server to control the mechanism. This way, when maintenance shows up, they can call my phone, and I can unlock the door when they arrive. I can ask them to press a button on the Arduino on the way out, so that it locks itself automatically after 30 seconds, OR, so that it notifies my cell phone and I can re-lock it from a distance.

    I have recently thought about building a cluster of sensors that responds to its surroundings and records/creates patterns. Those patterns then would in turn be used to create rhythms . The wearer could then play back sections of or whole of the musical score created. The device itself would take the form of jewelry or some wearable accessory. The resultant music or melody would be stored to an s.d device.

    I want to set up a self-watering system for my hops, using the Ardiuno to control a drip irrigation line fed by roof run-off from my pottery studio. And I want to make it capable of emailing me when the water barrel level gets low. And did I mention making it solar powered? That’s the plan.

    I’m in the middle of making a mind controlled arcade game. Where does the arduino come into play? I’m using it to get the data from the headset into my laptop so I can get the data into flash.

    I’d like to utilize a GPS sensor and build a hot or cold game played over twitter (you know the ones where you say if the person is hot or cold depending on how close they get to what they are looking for). Players would tweet their location and a hidden Arduino would listen and tweet back if the player was hot or cold in relation to finding the Arduino. The finder would win some sort of prize and then the unit would be hidden again.

    I have started working some with servos now, and would love to make a robot that can strum guitar at varying rhythms. I have started working on the project, but I think I need some different servos. The main project I want to build, is an autonomous vacuuming robot, with a cat seat built in. My cat used to jump on a skateboard that we would roll across the floor, so I think a roving vacuum would be right up her alley.

    then when they have 8 to 20 messages the second plate turns off and the third plate lights yellow;

    A LOT OF

    then when they have 20 + messages the third plate turns off and the fourth plate lights red:

    A TON OF

    My ideal build would be to hook every kind of sensor I could think of up to it and make a data logging tri-corder kind of thing. Ambient sound, Radio, speed, GPS tracking, wi-fi networks, geiger counter, UV meter, acceleration, light, everything. Then work that through a processing UI of some kind to provide an infographic of my day.

    Well, there are numerous amazing ideas already, so all I can say is, here’s why I’d love to have this kit. I have a dozen or so projects I’d like to do, but never have the money to buy an arduino kit to get started. Here are some of the projects I hope some day to be able to do:

    – RFID door unlock for keyless entry into my home
    – voice activated lighting, sound systems, etc.
    – moisture/temperature controlled watering system
    – Alarm Clock that turns up the volume on the chirping birds soundtrack slowly while also opening the blinds slowly, so that I go from pitch black to gently being woken up by the sun at whatever time I need to get up (assuming the sun is up).
    – A wide receipt printer connected to an arduino that triggers a print job with my daily to-do list each morning and a print job each afternoon with our evening meal plan recipe so the device can just sit in the kitchen, automatically prints, and I can grab my to do list each day, check it of physically as I go, and my wife can grab the dinner recipe, use it, and toss it when done (so she doesn’t have to have a computer open in the kitchen while she cooks). I’m sure I’d come up with many more uses for this device (maybe even start selling kits with the software to install on a local computer in the home network).

    I don’t have enough time to detail the others (still working, and need to get back to it), but this is just the tip of the iceburg of ideas I want to eventually do with an arduino kit. Don’t even get me started on the stuff I’d love to do with Lego :-)

    Hello World & Make! I won’t tell you much about my project- Artist Code- But, I just recently graduated from a master’s degree at SVA NYC and I’m still paying my tuition! So, I need an Arduino Board to complete a project made with water. The project is an interactive sound installation that will process real-time weather data from satellite and data from the user’s temperature. Through the auditory and somatosensory senses a deeper connection between the user and the piece will be established. Data from the user and from the satellite will merge into a sound composition. That data will also shape the form and the movement of the physical part of the installation.

I’ve put some thought into it such as type of controller, etc. I am considering taking an old laser or inkjet printer and using it as a base and adding on from there.

  373. Rotwang says:

    I modified a cheap toy RC car’s transmitter by replacing its switches with transistors attached to an Arduino. The Arduino receives commands from a Java web server that I wrote that also serves a webpage. The webpage uses JavaScript to send commands to the web server, so the car is controllable from anyone over the internet. I have a camera mounted on top that is wireless as well that is served to whoever is controlling the car via Skype. I had been using my iPhone with Skype mounted on top of the car which actually worked far better, but my friend in Canada who controls the car for me usually likes to fly off the stairs, so I found a mini analog camera with transmitter for about $20 instead.

    Once upon a time, I was chief software architect for DARPA’s Joint-Unmanned Combat Air System. We wrote some *really* cool software to fly these huge UAVs, but politics kept them from ever getting into the air. After scratching the autonomous air vehicle itch with a Blimpduino, I’d love to be able to take all the cool stuff we wrote and use it to fly a bunch of swarming, autonomous winged aircraft. Arduino would be an awesome platform for this project, since all of the hardware for air-to-air comms has already been baked into some nice shields. Just need a development platform to get it all started!

  375. Alex Boyd says:

    I hooked up a microcontroller to an rs232 bluetooth radio, and wired every switch that is in my Mini Cooper to the microcontroller and then I added up a start button and took the key out of my car. Then on the other end of the bluetooth I interfaced to my phone so my phone became my car key. I could then remotely control everything about my car except for the driving. I did this 5 years ago and the microcontoler is very outdated, so I would like to use the arduino and update my car.

    I made a full color audio spectrograph to visualize ambient sound or music. I built and connected a RGB LED matrix to an Arduino programmed to compute the FFT of continuous samples taken from an amplified microphone source. Each result of the FFT was plotted as the rightmost column of the display with color representing the average magnitude in a range of frequencies corresponding to that particular row. Each iteration also shifts the previous image on the display left by one column meaning that the final output was a continuous scrolling spectrogram. I want to scale this up to be an installation piece like 50×200 LED’s – big enough to put on a wall at some kind of party or show.

    For an Aerospace Engineering class on weather balloons, we were assigned to devise our own “mission” and payload for the balloon to accomplish said mission. Everyone else in the past has done boring stuff, like measuring weather data, or taking photos of a plush school mascot in near space. My friends and I decided to take it to the next level. We are dropping from a yet to be determined altitude (ITS OVER 9000), an arduino/ardupilot, automated glider which will find its way back home. We’ve got the ardupilot and glider pretty well done, but havent flight tested it yet. We need, very badly, a second arduino to operate the balloon’s gps tracking, radio transmitter, release mechanism for the glider, and automate the recording process for the video camera that’s going to tape our glider being dropped.

With luck, I’m trying to make one small and light enough to fly in the office. If that works out, I’m going to try to build one big enough to fly a pocket camera around outside.

    The thing uses accelerometers & gyros to keep it stable and control the 4 motors so it can be hovered and flown more easily.
