Hi,
Just designing some equipment (bit of hardware + micro) which I need to remotely control.
I need to send a few signals to the equipment, within say 5-12 feet, a lot like a TV remote in terms of distance, but a lot less signals - probably four distinct messages will be enough. Also, signals are low speed - say one signal in 1/4 second is all I need. Probably a good idea too if TV remote doesn't interfere with my equipment too.
Any recommendations/pointers?
TIA
Paul.
