Many inventions/hacks often arise out of the need to solve a problem. The Arduino mailer notifier project was no exception. My workshop is in my backyard. During the day, I am far away from my mailbox. Using two Arduinos, some cheap RF modules, and a light sensor, I was able... Read more »

When you hear the word "wirebot," you likely think of those cameras racing along wires above sporting events, unobtrusively capturing amazing action footage. Our wirebot will be quite a bit simpler, and a lot cheaper, however it offers quite a few cool possibilities. Some of these applications include things like... Read more »

Using the Arduino development platform you will learn how to display numbers and letters on a single 7-segment LED display. There are many ways to drive 7-segment displays, and this is a fairly simple method. However, using this method to drive even one LED 7-segment array "burns" (occupies) many of... Read more »

When I first started working with microcontrollers, I had an Arduino, a few LEDs, a handful of DC motors, and very little common sense. :) I learned firsthand that if you did not read before you wired stuff up, it could be a costly mistake. However during my hardware infancy... Read more »

If you’ve ever wanted the ability to use some form of hardware-based authentication in your projects then this is the board to do it with. The Parallax RFID (Radio Frequency Identification) reader is super easy to configure. It only takes four wires! It uses serial protocol to transfer information from... Read more »

This fun and easy project shows you how to create a simple input device with little more than a cheap piezo sensor, an old mousepad, and an Arduino board. Using household supplies and a few passive electrical components, you can create a basic physical-computing game input device for your Arduino. Read more »
