Hi, I'm a relativelt inexperienced electronics hobbyist and have am looking for a rf circuit to fit a certain need.
What I'd like to have, is simply one circuit(a) which will emit an rf frequency, and another seperate circuit(b) a few feet away, to detect circuit (a)'s transmission.
Basically a very simple remote control, press a button on one circuit, and have it effectively turn something on in another remote circuit. Also, the smaller, and simpler the better.
Any help will be much appreciated, thanks a lot.
