Thanks for the info! It looks like garage door openers are pretty pricey and also quite bulky though. Maybe it would be easier to just create an arduino compatible circuit on the transmitter side, something like this: http://arduino.cc/en/Main/StandaloneThat way I will not be wasting an entire arduino to just sit in a remote forever. Would that work? I have never built a standalone arduino circuit before - are there any limitations to such a circuit, or if a program works on a regular arduino board it will work on the circuit 100% of the time?Thanks!
I'm working on a project which will need a one way wireless switch. Basically, the arduino will have a receiver and it will "listen" for a specific signal, and when it receives that signal it will trigger an action. All I need is a simple triggering mechanism, not two-way communication.
