hi all
i'm looking for a simple transmitter and receiver circuit 9 volt
it's for a humane mouse trap when the trap door closes i want a signal sending to a simple receiver so i can tell that the trap has gone off its around 20 meters away.
if not i would like a simple transmitter circuit so a signal is sent to my fm radio
all the circuits i can find on the net use an electret mic i just want a simple tone
any help would be appreciated with links
