I made an Arduino project that decoded infrared signals from my remote control, and it was so much fun that I kept optimizing the code. This new video demonstrates some of the added functionality, but more importantly, I provide specific details for how to replicate this circuit on your own. If you have an Arduino and a breadboard, then you can build this project for about $4. All you need is an IR Receiver from RadioShack (part # 276-640).
