This IR remote control circuit Transmitter use IC Op-amp 741 is pluse generator for Triggered SCR which is connected with Infrared LED. When we presses a button SW on transmitter IC op-amp 741 are generator square wave The IR signals sensed by the infrared LED to Receiver
Figure1 Schematic of of Infrared Remote Control (Transmitter and Receiver )
Infrared Receiver
The infrared signal from the remote control is received by phototransistor which is connected with Op-amp 741 for driver relay
