“Tiny DIY programmable IR remote that’s based off the arduino uno (backwards compatible with my orginal Remoteduino project)!
Basically a more refined version 2 of my original Remoteduino project, which was an arduino compatible programmable IR remote. The nano is even smaller and adds an onboard IR receiver to allow programming buttons on the fly from other remotes (software is still a work in progress on that front, but hard coded remote commands currently work).
