Hi Guys,

I'm simply needing a very basic radio-controlled switch, with probably a 100' range ...just a single channel. No data or anything...just push a button on one end and detect it at the other end.
please give me any link or any circuit for it.
I try myself but didnt findout in last an hour.
please help me out

 

Try adapting one of those remote doorbells or something along that line. It's difficult to design and construct RF circuits.

 

well, i was looking for Garage door opener but i didnt find out any circuit for it.

does anybody have any circuit or link ??

 

Everyone wants to sell one, not many circuits but this seems to be the best search so far:
