Hello everyone,
Nice to see a good forums related to electronics.
I'm wanting to make a small circuit that transmits a signal. This signal will be received by a receiver and when the receiver is out of range of the signal the receiver should be able to drive a transistor to start another circuit.
All the circuits and stuff i read on this type of thing are for transmitting audio or data. My plan is to have a peizo buzzer and some leds on a cats collar and when/if he escapes the buzzer will sound and the lights will flash so I can find him. So the circuit needs to be pretty small.
I'm thinking I will need to build a oscillator of some sort to transmit the signal.
Can someone recommend some reading and/or suggest a circuit ?
Thanks In advance !
