An IR transmitter and receiver pair forms a simple circuit. This project explains the principle of IR communication. The 555 Timer IC operates in an astable mode. It generates the continuous pulses of the frequency. As the switch is pressed, the connection between an IR LED and the 555 timer IC closes. Then the IR LED emits the light of some frequency.
