This project is developed for the users to control the operations of a fan using remote control.

The remote control system works by the use of infrared signals. The transmitter section of the system produces and transmits infrared signals. These signals are received in the receiver section that is placed in the receiver circuit of the device.

Four relays are connected with the receiver circuit and are connected with a wire wound variable resistor. The fan is connected with the N/O of the relays.

When the user presses the button in the hand set, the transmitter transmits IR signal. The receiver receives the signal and sends to the Flip flop IC. The IC controls the driver section to operate the relays for the operation of the fan. By this way, the user can control the speed of the fan in wireless manner
