I was wondering how to build a receiver circuit that detects the output from any of my pile of remote controls.
I can give you specifics on the remotes, if needed, but it would seem that any of them could be used to trigger an on/off switch remotely.
I'm assuming the transmitter is an LED diode flashing some pre-programmed sequence. I can see the flashes using my camcorder. Seems like if I bought a cheap RadioShack LED receiver, I could then build a circuit arond it that would toggle ON/OFF.
I'm not an EE, but I did take EE (DC and AC) in college.... which means I know just enough to be dangerous. I promise, I'll just use AAA batteries and a well-grounded screwdriver.
Assume, for discussion, that I want to turn a flashlight bulb on and off using the TV remote.
Thanks.
