Hey guys,
I'm looking for some help.
I want to find a way to have a RF transmitter/Receiver circuit know when its getting close to its brother circuit.
I.e. in pretty rough terms.
You could put the "gadget" in your car as you leave it in a parking lot.
Then as you come back to the lot to retrieve your car, your brother "gadget" (on your person) could light up as it receives the signal from the one in your car.
I'm not looking for pinpoint accuracy, just something that lets you know your near.
