Automatic control of home appliances is highly demanding now a day .In this works we have designed and constructed a circuit which especially meet the requirement of control the home appliances through any remote control device that is portable within the periphery of the room. The device is able to control a load of high power rating from remote area. The system works satisfactorily and it is also considered to be a cost effective system. This device will make our life become easier. We can easily control three devices like 2 lights, 1 fan from the distance of 11 meter by remote control. We don’t need to go near the switch board then turn the switch on. We can control them easily by remote from 11 meter distance. The most special feature is we can control the speed of fan for nine times. In case of remote failure we can use it as like as normal switching device. I think one day it will be the most attractive feature of our digitalized life. KEYWORDS: Microcontroller, home appliances, automatic control, cheap installation cost.
