Here is a system which provides you a remote control in your hand ,to operate your electrical equipments .

This remote control is your mobile phone ,which also works as a remote control.

What is this?

Actually you can control your electrical equipment with the help of your mobile .

You have to give a MISSED CALL or send an SMS from your mobile phone to a specified number,that will be given to you. The MISSED CALL given by you will switch on your appliance,.like fan ,bulb ,A.C etc

BASIC CIRCUIT:

Every communication system needs a receiver and a transmitter .

So here your mobile is a transmitter and receiver is a main part of the project, that will receive signal and convert the signals into electrical form which switches your electrical equipment ON or OFF.

The block diagram is shown here.
