So I have a learning remote control that doesn't work that well anymore. I want to use the IR LED in it to act as an IR receiver, then use another IR led to act as a emitter. Yep, you got it, I'm trying to build an IR range finder (more like an IR wall detector). Anyone know anything about Learning remote control IR LEDs?
Yes I will eventually buy IR rangefinders for my bot, but for now, I have no money, and I want to see if I can figure this one out.
EDIT: If you don't know what a learning remote control does... well, you push a learn button, then use another remote control to emit the frequency you want, then whatever button you tell the learning remote to use that frequency for, it will.
