The picture above is the circuit diagram that we want to modify for the remote control. Four 6 volts relays used to connect with the push buttons at the remote control circuit. Relays function as a switch to operate the remote. For this circuit, we use 5 pins relay. Relays have two circuits which are a control circuit and a load circuit. The relay's switch connections are usually labelled COM, NC and NO:
COM = Common, It is the moving part of the switch.
NC = Normally Closed, COM is connected to NC when the relay coil is off.
NO = Normally Open, COM is connected to NO when the relay coil is on.
