Thank you for the reply guys,
@billhowl, that is actually pretty good, and i am definitely buying it.
It was actually a college project and obviously has to be more of something that you make from the parts available,
I bought the Sparkfun Transmitter/receiver pair(434MHz).
Could it be possible to hook up the transmitter, such that it takes in a digital input(limit switch), without using a micro.
And send a signal to the receiver which gives a digital output!?
