Infrared remote controls have been used now since more than two decades. The control unit is an integrated circuit which is designed to detect such changes in the flow of electricity and send a binary code for that specific operation to the receiver unit in the TV set. Usually, this means each remote control system can operate only one TV made by only one manufacturer. An IR remote control (the transmitter) sends out pulses of infrared light that represent specific binary codes. Locate the Infrared receiver on your TV set or device.
