anyone know of a good diy wireless circuitry instructable? Answered

I'm looking for something that shows me how to turn something on and off with a pic or other microcontroller.?


HOW wireless ? IR, 433Mhz radio, Wifi ? Single channel on/off ? Multi ?

I guess I could have been more clear. I know I want radio, not IR, but beyond that not much more. I don't need enormous range, but up to 300 feet line-of-sight would be nice. Simple ON/OFF, single or multi-channel, but serial data transmission would also be nice.

So, since I didn't really narrow it down that much... Anything?
