This is the schematics for infra-red remote control Receiver. This remote control receiver will be able to receive a transmitted tone from it's respective transmitter's infra-red LED. And this received tone will be decoded by the receiver. Since the receiver only switches when it "hears" the tone, there are no accidental activations.
- To adjust the circuit, hold down S1 while pointing LED1 at the receiver. Adjust R6 until you hear the relay click.
- You can increase range by using a high output LED for LED1.
- Bright light will stop the receiver from responding to the transmitter.
