Abstract
The project is concerned with the design and construction of a remote control system for an extension wire using infrared frequency remote control as the transmitter a free space to the receiver circuit which has infrared detector module that work as the main receiving module is used as a trigger to a monostable multivibrator built using 555-timer IC. The output of the multivibrator is used to drive a decade counter (IC 4017) which is wired as a toggle switch. The output of the 4017 toggle switch is used to put on and off the extension wire connected through a relay.
