Getting Started with Arduino Book Giveaway

In support of our Arduino issue of MAKE, Volume 25, and our new Make: Arduino landing page, we’re running a book giveaway. If you don’t have Getting Started with Arduino in your library, and you’re interested in understanding Arduino and how to get into the world of interactive devices (or if you’re already an Arduino enthusiast but want an evangelical tome), you need this book! Written by Massimo Banzi, a co-founder of Arduino, Getting Started is a real joy to read and to use. I was so tickled when it first came out, especially when I read the intro section which tells the fascinating story of how Arduino came about and also serves as something of a high-tech maker’s manifesto, with brief sections on prototyping, tinkering, the joys of junk, and toy hacking/circuit bending. The rest of the book walks you through understanding the hardware and software of Arduino and how to set up various types of sensors to create “interactive devices” that can sense the world and respond.

We have five copies of Getting Started to give away. To be eligible, all you have to do is post a comment below on the theme of: Everything I always wanted to know about Arduino, but was afraid to ask. What are some of the nagging questions you have about Arduino, from the conceptual to the specific — no question too basic or advanced. And, as with our recent Make: Electronics book giveaway, you can also help (and be eligible for a book) if you provide answers to questions posed here. Let’s crowdsource an FAQ on vexing Arduino questions.

We’ll run the contest through next Thursday, 11:59pm PST. And we’ll announce the five winners next Friday. Good luck!

Update: And the winners are: Gene Kaufman, Rob T Firefly, Liz Valentine, Michael Voss, Crow. Email me to claim your book.

Don’t forget to check out our Make: Arduino page for all sorts of microcontroller goodness.

    Is Arduino for a LEGO MINDSTORMS NXT user?

    • http://www.facebook.com/people/Billy-Stevens/100000613974573 Billy Stevens

      I went directly from mindstorm NXT to arduino and it took some getting used to and even now I haven’t gotten too advanced but it definitely is possible

    I’ve been wanting to get into Arduino for a while now, but haven’t found a good enough idea to justify the time/money… I really just need to dive in and experiment. I recently started a gigantic desk, and I think i’d like to have parts of the desk react to events from my computers, but I have no idea where to start coupling mechanism to the computer. Are there several languages you can program the instructions in? Also, how often do people use the Arduino as a prototype, then replace it with a custom built solution, or do people generally continue to use it in an application, then just buy another for the next project?

    • http://www.facebook.com/allen.pinkley Allen Pinkley

      I was the same way. Just do it. Get a starter kit and tinker with their examples. As you work through the things ideas will come to you by “if it does, can I do?” type things. I can deal with the wiring but now i am starting to get into code that I haven’t thought of in years.

      • http://www.facebook.com/bobclagett Bob Clagett

        cool, thanks for the response… I might just do that..
        I’m a programmer, so I’m really looking forward to that part of it :)
        Thanks!

    I’m an 11 year old girl who has always been interested in arduino, but never known how to ask my dad or convince him that it’s worth the money. I’ve already done a lot of programming in scratch, so my dad knows I like computery stuff, but asking him to buy me something new and random-seeming and help me with it has always seemed very hard. Help?

      Download the arduino software, and write some scripts with it. Download an emulator http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1279791354 And test them there. Show them to your dad.

      That will show your dad that you have initiative, and that you are already have specific projects or programs made. This should prove that you are not just getting a board that will gather dust in a corner.

    What the heck does the ICSP do for me on the arduino?

    • http://twitter.com/SiliconFarmer Greg

      The ICSP can be used to replace the Arduino boot loader. For example, if they have an upgrade to the code. Or perhaps to do a project with the board completely with your own code without the Arduino boot loader present.

    • http://www.facebook.com/ethan.dicks Ethan Dicks

      The ICSP is how you can program a blank AVR microcontroller to install the “bootloader” (the program that comes on a ready-to-use Arduino that knows how to load your programs (sketches) over the USB/serial port. You can also update the bootloader on your working Arduino with a newer or different version, though that’s not often needed. Lastly, if your project is so large that you are filling program memory, you can dump the bootloader entirely and load your entire program over the ICSP port.

      You’ll need a programmer of some kind to use the ICSP port. The USBtinyISP is an inexpensive ($20) way to go these days, but there are older programmers you can make from scratch if y ou have a real parallel or real serial port on your machine. Once you have a programmer attached to your ISCP port, ‘avrdude’ can get your new/replacement bootloader or your application directly onto the chip.

      Most Arduino users never touch the ICSP port, but if you start to build dedicated AVR-based projects, it’s quite handy.

  • http://www.facebook.com/gordon.currie Gordon Currie

    Whats exciting for me about the Arduino is it bring sback my introduction to electronics with Radio Shack kits. Jump ahead 40 years and my son and I are sharing ideas on things we can experiment with using the Arduino. My relationship with my son is only getting better and I credit the Arduino and MAKE: as the glue that makes it work. Its also such an economical way for people (youth especially) to get involved and jumpstart careers and life long interests. Way to go Arduino!

    “Are Do We Know?” I am much more “Are Do We Not Know.”

    I constantly read about projects here and on other sites that would be fun to do, and I have a few ideas of my own but I know that I would need a book like this to walk me through it all. I’m computer savvy and pretty handy but the arduino just seems like it’s too far out of reach for me. Arduinot?

    Here’s one thing i would love to do. I want to control the curtains in my bedroom. I want them to open up in the morning with my alarm clock. I want them to close at night before bed. But I also want them to close depending on the weather. Open and let the sun in during a winter day that is sunny but shuttered against the cold otherwise. Perhaps on a summer day open until the room reaches a certain temperature and then closed to block the sun if it gets too warm.

    I think an arduino can do all this pretty easily right?

    Will the Arduino boards return to easily swappable chips or are the SMD chips here to stay?

      Looks like you’re all ready to get started.

      It depends on which flavor you get, but the most popular boards have female single-row headers down each side where the I/O pins are brought out. (See the photo of the Uno at http://www.arduino.cc/ for example.)

      Some of the other flavors have solder points for the I/O lines (http://www.sparkfun.com/products/9712), and yet others come in a DIP package ready to plug into your breadboard (http://www.sparkfun.com/products/8164).

    I’ve got two sons (12 and 14) that are really smart and ready to learn! I’ve want them to understand how an arduino works so that we can make projects together and explore the world of electronics together. I would love to have the book so that I can pass on knowledge to them in a way that they can understand (and me as well). We just did our first project together and it was a proud moment for them and me. Hot cross buns using the tone library – pwm is now understood!!! I think that what we can pass on to the younger generation benefits us all… Kids attention span is short now days and having this book at my disposal will give me the chance to show my sons the world of electronics and allow them to use their imagination to create things beyond their imagination — OK… maybe that’s a little out there… but, kids, arduino, imagination… who knows what’s next!!

    • http://mattrichardson.com/ Matt Richardson

      The book Getting Started with Arduino is a perfect place to start. A perfect companion is any kind of Arduino getting started kit, which usually includes a basic Arduino board (usually the Uno nowadays), jumpers, a solderless breadboard, LEDs, and a few sensors.

    I’m something of a klutz and I get the feel that with so much exposed surface on the Arduino, the potential for me to shock myself or burn out the unit seems kind of high. Does anyone know how likely this is?

    • http://mattrichardson.com/ Matt Richardson

      It’s not likely that you’re going shock yourself or burn out the unit. They run on around 5 volts, which is pretty low and they’re very robust. My Arduinos have definitely taken a beating, but I haven’t had a single one fail.

  • http://www.facebook.com/people/Michael-Saz/1613731776 Michael Saz

    Well, I wondered if it’s as easy as it looks! Easy enough for a lapsed maker from the days of TTL to get back into. I also wonder what’s the fastest sort of processing that the arduino can handle, for simple real time-ish interaction.

    My biggest question is “What can I make with an Arduino?” I am amazed to find all the new things people think of to make. It’s kind of like asking what can you make with a hammer or screwdriver. I’m amazed daily about the things that people are creating and the things I’m learning. I’m learning electronics just by reading about other peoples projects and tutorials. I use parts I’ve salvaged from discarded electronics but haven’t been able to buy this book yet because of my low fixed income. I have an Arduino now but I think this book would help me learn a lot more.

    I’ve wondered about the Arduino origin story. The choice of the atmega8 seems inspired, not just because of the progression to 168 & 328 but when you go up or down from that sweet spot in the avr family you seem to lose more than you gain: i.e. the sanguino has more function but it’s awkwardly big; the tiny’s are great but you give up the uart, interrupts etc. Also, the board design is excellent with the headers for connections and the overall build quality.

    so tell us, how did the design process work, or did it spring full blown from someone’s imagination?

      There are a ton of great projects that require no soldering. All the projects in this book don’t require soldering.

    • http://mattrichardson.com/ Matt Richardson

      I would recommend you start with the Arduino Uno, it’s the most standard and up-to-date board. It’s also compatible with pretty much all the shields out there. Helping you find a first project would be tough. I pretty much played around with the components in a getting started kit for a long time. When I was ready to get more advanced, my first project was hooking up the Arduino to a receipt printer to print my Twitter @ replies. I would say play around for a while and see what area interests you.

    • http://mattrichardson.com/ Matt Richardson

      You’d want to at least solder those header pins onto the board so that you can put it into a solderless breadboard. Then you can use jumpers to connect the Arduino to the LCD. As a matter of fact, my first crack at soldering was putting header pins on an LCD, and it was a lot easier than I thought it would be.

    • http://www.facebook.com/people/Leif-Burrow/100002078415057 Leif Burrow

      Without a chipset the display requires a lot of pins. So long as you don’t need many pins for the rest of your project you can get really cheap 2 line LCD character displays this way. For a bit more money you can get a display with a chip and it only requires 1 Arduino pin. (They say 3 but the other 2 are power and ground).

    • http://duncanmurdock.name/ Duncan Murdock

      The Arduino is programmed by a special language called (unsuprisingly) Arduino. It’s based off of C++, and i believe straight C++ code can be used. Arduino’s strength comes from the hundreds of libraries built for the language, which make coding a snap.

      You can use Arduino’s to do anything! Some cases may require beefier controllers like the Arduino Mega, though. Anything that requires more than a Mega might be better handled by an ARM.

      About the other stuff, it’s over my head, but I recommend the USB BOArduino or Arduino UNO for boards.

    Is there any plans to increase onboard memory size, and over all capabilities and ranges of some of the commands, ( have some projects using Tone command but its range is limited on the low end to no lower than like 31hz, and just so happens I need lower) I am using delay and such to get lower, but seems as though they could increase usable range .

    • Anonymous

      More traditional microcontroller manufacturers… the first that comes to mind is PIC. They make many dev kits for use with their microcontrollers and were probably the king of the hill before arduino came along and stole the party. Many people also work with the Basic stamp. A new competitor that is gaining traction is the Beagle Board — since it has a much more powerful microcontroller on it, it can handle a lot more.

    • http://www.facebook.com/people/Leif-Burrow/100002078415057 Leif Burrow

      The Parallax Propeller is a big one in robotics circles. That one almost straddles the line between microcontroler and single board computer though, in fact it is also used to make a hobbyist game console and various retro-computers.

      Pic was the big one in the other hobby markets.

      TI has the MSPP430 value line. They are not as powerful but they are going after the hobby market by trying to undercut everyone’s prices. They are cheap.

      I don’t think I would count the Beagleboard among Arduino competitors. It’s really more of a single board computer, most of them end up running some form of Linux on them.

    Information about the clockrate, how that translates to the speed that your code runs, etc. Having done low-level programming I can make a guess, but it could be helpful for the people who haven’t taken classes on microprocessor and computer design.

    Some tutorials on the ‘how-to’ of designing the circuit that would go between the Arduino and your project could be useful – i.e., some basics on turning digital logic into the less ‘simple’ outputs. (e.g. Motors -> need a motor driver, why, how, etc:). To put it another way, what are the limitations in terms of current per output, voltage levels, etc for the various outputs, and if I’m looking at a datasheet, what do I need to look for to get a component that will be compatible. Safe practices to protect the Arduino, that sort of stuff.

      I think it depends on the child, but I have shown projects to my 8 and 5 year old. They even find the LED blinking to be great. Just be ready to take over the project if they seem to lost in it. They will enjoy themselves even if all what they are doing is watching you work on a project and asking questions. Let them compile the programs and load it to the arduino. Even a minimal involvement makes them happy and makes them feel like they contributed.

      My personal belief is that young kids will remember whatever they were exposed to when they were little with fondness. So the earlier you expose them to electronics or programming, the more they will have that fuzzy connection for the rest of their lives with the subject.

    Can you reuse an arduino controller or is it pretty much a one and done situation?

    • Anonymous

      You can reprogram and reuse the controllers over and over. That’s the beauty — you can easily prototype/change/extend your projects — and if you end up building something good enough to keep for posterity — just buy another controller, since they are so cheap. If your project was more of a gee-whiz fun thing, and isn’t needed long term, then by all means, reuse the arduino in your next project!

      An analog pin can be used just like a digital pin however it also has an analog mode. If used as an analog input it can measure a voltage between 0 and the supply voltage. This is great for using analog sensors. As an analog output it outputs pulses where you can control both the duration of and time between each pulse. This is good for controling servos, dimming LEDs and more.

    How can i keep a Raccoon out of my house with a smart dog door?

    • http://www.facebook.com/people/Andreas-Mueller/679408071 Andreas Mueller

      Something like a RFID chip around the dog’s neck, the Arduino unlocks the door when the dog is close. Then you need something to detect that the dog is inside the house to lock the door again.

      • http://twitter.com/ThomasSloan Thomas Sloan

        Maybe a RFID reader on both sides of the door. Just have the default state of the door at locked and when the dog approaches the either side of the door (to go in or out) the door unlocks for 10 seconds and then locks again. The only down side is if the dog loses the collar or something happens to the RFID reader and/or Arduino then your dog would be locked out (or in).

    I have yet to build an arduino project, but I have an idea that involves storing at least 6 numbers between uses. I’m thinking about using an SD card. And my display will be 4 2-digit numbers, 2 3-digit numbers, and at least 2 LED indicators (only one of which would be lit at a time). There’s also a need for 2 buttons and some type of reset capability. I’m a web programmer, so the actual logic that will be used is all pretty clear in my head, but I don’t have any idea about how to read/write to the SD card (if that’s even the best alternative), or how to drive the display (also: 7-segment LED’s vs. LCD?). Is this all covered in this book?

    • http://www.facebook.com/people/Leif-Burrow/100002078415057 Leif Burrow

      I believe there is a library for reading/writing to an SD card. On the hardware side you would probably use the serial interface which involves just connecting a few pins. One way to get a socket for it is to get a mini/micro sd to fullsize sd adapter, solder wires to the adapter and use the smaller device. Sparkfun also sells a breakout board with a fullsize sd slot on it. Or.. you can remove the socket from a cheap SD card reader.

      But… why do you want to do this? There is already an eeprom built into the chip. Space is limited but from what you describe should be a non-issue. Try this: http://www.arduino.cc/en/Reference/EEPROM

      • http://pulse.yahoo.com/_HWK4DAEQQFDG2AYEMWO5V56DHY Javen

    What’s the best way for me to use an Arduino to monitor the water level in a sump well? I’ve considered a float but space is limited and I am afraid it will get stuck on something or gummed up with algae and fail. I’ve considered electrodes but I want an actual level reading, not just a yes/no it has reached a certain level. I even thought about slanted electrodes that are closer together higher up the hole then measure the resistance but that would depend on the amount of electrolytes in the water to be constant which I don’t believe it is. Finally I’ve considered using the capacitance measurement library and two metal plates with a thin plastic coating to insulate them from the water. The dielectric would be part water part air depending on the height of the water. Would this work or would it also vary based on dissolved electrolytes? Has anyone else done this?

    How many buttons can I hook up to an Arduino? What is the best method? I need to be able to register more than one button push at once.

    • Anonymous

      Directly you can hook up as many buttons as you have free digital pins. (you could probably even get creative with an analog input to accomodate a switch also) If you need more, using some external logic gates or even an FPGA might help with that.
      As far as reading more then one button at a time, this can be tricky. On a small scale what I’ve done is written one routine (is that an old term?) that reads the states of all the button and stores the result in their respective varables. A second routine that reads all the variables and takes the approprate action based on the state of the variables. I have to assume if you had a TON of button inputs you may run into processing speed issues especially if you are using a software debounce on the inputs. There is probably some fancy Arduino-thing that can handle this better but this is probably the approach I would take.

      Example:

      {…

      read button 1
      if pressed button1_var = 1
      else button1_var = 0
      read button 2
      if pressed button2_var = 1
      else button 2_var = 0
      read buttton 3
      …button 4…button 5 etc…

      //deal with the state of the variables

      If Button1_var = 1
      Do whatever button 1 does
      else do nothing
      if button2_var = 1
      Do whatever button 2 does
      else do nothing

      …etc.

      On the hardware level they use what are called shields. Basically they are boards that usually plug on top of the Arduino and then the device plugs into that board.

    Analog circuitry is pretty straightforward. Everything is just a voltage or a current, and you can verify your math with a multimeter. In essence, digital circuitry is even simpler than analog since you need not worry about whether a voltage is 5.1 V or 5.2 V, it’s “high”. A lot of electronics today are digital, like cameras and displays. How can the average hacker integrate an LCD display or camera extracted from an old cell phone into a project?

I’m looking to get into Arduino though as it has more of a user community and more sheilds (for now anyway, Netduino is catching up in both those areas).

    You’ve made your cool project ( Arduino + breadboard + parts ). Now you want to make it stand alone. How can you build your own Arduino type board? Would like to just order an ATmega328, and build an inexpensive board. Then keep using my Arduino for more development.

    I would like to see a book focusing on Arduino entitled, “Fun and Cool Projects You Can Do With Your Kids”. Maybe there can also be a contest to submit ideas for the book and the best ones could be published by Make. I would love a copy so I could participate in such a contest, or just to get started and have fun since this is new to me.

    “Everything I always wanted to know about Arduino, but was afraid to ask. What are some of the nagging questions you have about Arduino, from the conceptual to the specific — no question too basic or advanced”

    Well, Im new to the arduino, I genuine newbie , Id like to ask, can you use interrupts and the internal timer at the same time? or is the timer disrupted? if not is there a work-around?

    can the Arduino outputs (the AVR outputs) be used together to drive more current? i.e. you tell 4 outputs to go high to drive 80mA into a load?

    I think in mechanical 3D sense, a gear, driveshaft or even a relay makes sense. Getting into the programming side has seemed daunting to me. I can build almost anything physical, but taking the step to get under the hood and programing something to do a task is a skill I want to learn, yet…. I have no idea where to start with Arduino.

    I’ve wanted to try making something with Arduino since they first started cropping up in knitting projects and clothing a couple years back. But I don’t have any experience with electronics beyond rewiring a table lamp and I’ve wondered if, once I bought some Arduino basics, I’d really know what to do with them. It would be fabulous to have a book like this – it’s exactly what I need to enter into a new craft/skill with confidence. Thanks for holding this giveaway!

    Would you have to be an Arduino whiz to make a sensor that tracks when stray cats enter your yard to poop in the garden? I don’t want to put up a fence all around the property and cat poop is super stinky! The sensor would then deploy something cat-safe like a water gun to discourage them from entering the yard. Even better would be to allow my guinea pigs to free-range in the garden so they can manure the yard on their own while eating weeds- no cats in the yard would be necessary for this. Guinea pig freedom via Arduino, it could be called.

    I have a need to precisely control the speed of a diesel generator. While this may sound trivial, it’s not, and it’s expensive to have the injection pump recalibrated. Currently, I have the throttle locked to a specific spot, which works sorta well I was looking for a way to control the throttle electronically, when someone suggested using a Arduino.

    My ideas are pie in the sky… automatically start the engine… read fuel, water, oil, and current sensors… manage throttle… and, if anything goes wrong, shut the engine off.

    I’ve never programmed ANYTHING before, and this looks like a daunting task, but I think I’m up to the task. For me, hardware is easy… the tricky part is the software. My Arduino is in the mail, and I already have a basic layout of a sketch. Now, I just have to figure out how to get it done. Suggestions???

    • http://twitter.com/rileyporter riley porter

      Suggestion is do not start with that project. Start with easy projects.. Get the Make book and go slow. Then read more blogs / tutorials and move up.. Next thing you know you will be able to use a light sensor or perhaps a rotational encoder to measure “rpms”. :)

    We have a few projects we are looking to jump into that require a micro-controller. I have an old Radio Shack Armitron we want to automate. I have a fiberglass shell that looks amazingly R2D2 like that we would like to make an RC (full size). We would like to build a Rube Goldberg device for display in the school hallway to teach the basics of machines. All of this seems to point to the Arduino as a viable platform which I know very little about. This looks like a great way to do that!

    Can you give me some ideas to correlate what I am learning in my college algebra class with how arduino programming works? I checked out a book from our library on C++ programming and have to say I’m not really sure where to start and I’d like to have a good idea if this is something I can handle without getting frustrated before I sink too much money into it. Extra bonus points for working in small steps/projects/concepts a five year old could help/work with ;)

    I see alot going on with the Arduino for a while now. I’ve been playing with the basic stamp controllers. So, what makes the Arduino better then the Basic Stamp series controllers??

    • http://twitter.com/restifo Christian Restifo

      Two things in my opinion:

      1. Cost. Arduino starter kits are much cheaper, especially if you make them yourself. Open source goodness and all that.
      2. Libraries: It’s been my experience that it’s a lot easier to locate a library for something with an Arduino (LCD, servos, serial communications, IR receivers, etc.) than a BASIC stamp.

      I have a Basic Stamp, and it just seemed too difficult (compared to the Arduino) to get it to “do stuff.” I think that’s the major draw for new people since they want to concentrate on doing something, not learning the programming intricacies of whatever chip they’re working on.

    Although I have been a hobbyist “maker” for some years, I have recently started doing more intense Maker projects, the latest of which has been finding uses for every salvageable part of an old dead laptop.

I’m very excited to do this, but I’m not sure where to start. This “Getting Started with Arduino” is exactly the resource I need. It may even teach me how to correctly pronounce “Arduino.”

      Yes you can. The “firmware” is available right through the Arduino IDE. You need an AVR programmer. (You can use another arduino to do this.. however I have never done it) Hook up that programmer.. Connected the Arduino to a power source and then click the option that says “burn boot loader”.. Thats it..

    Now im currently using ARDUINO to teach to other students how to make his dreams true… quick and low cost.

    One recomendation for the begginers… use: virtual breadboard, for simulations of your proyects with ARDUINO.

    There is a “Make” video which shows how to control LEDs brightness to chance colors etc with an android device. In the video, they used the device as power source.

    I wonder if I can control the LEDs with the device (with a wire or wireless) and still power it up somewhere else?
