We’ve got a bad case of Arduino fever over here at Gearfuse and some homebrew projects are our only cure! That aside, you can now use a code library to use a universal television remote to control your Arduino-based project. The official word:
The library implements the NEC IR protocol, so set up the universal remote for any NEC device (TV, DVD, VCR, …) and the 32-bit codes should be received.
The example sketch provided just prints out IR codes as they’re received, so it’s good to run that sketch to see what codes the remote is sending, so they can later be used to trigger specific actions
If you’re currently working on an Arduino-based project, this is a must see.
