"Remoteduino Nano: The Ultimate Universal IR Remote"
The Remoteduino Nano is a fully programmable IR remote that allows users to map eight buttons to any desired code. It runs on an ATmega328p and includes a five-pin header to program the device through its serial port. The tiny size of the Nano makes it a convenient tool for those who like to tinker with A/V systems and keep losing their remotes. The project's code and Gerber files are freely available for download.
