Hi

There are some cheap RF RX and TX modules available. Any circuits out there for pic to pic transmission. Need to turn led on or off over distance of about 5 metres.

Just the transmission details I need.

There's some examples somewhere around there.
Might have to have a fairly strong IR LED transmitter though.
