红外线远程控制电路 infa-red remote control
i have received a number of emails requesting schematics for infa-red remotes. so here is one. this remote transmits a tone using an infa-red led. this tone is decoded by the receiver. since the receiver only switches when it hears the tone, there are no accidental activations.

notes:
1. to adjust the circuit, hold down s1 while pointing led1 at the receiver. adjust r6 until you hear the relay click.
2. you can increase range by using a high output led for led1.
3. bright light will stop the receiver from responding to the transmitter.
