INTRODUCATION
1. All the electric appliances will be controlled automatically.
2. We can control many different devices like AC, projectors, lights, fans, air conditioners, television e.t.c
3. A central controlling unit will be established.
4. The interface for the data transmission would be the Bluetooth.

MICRO CONTROLLER
1. Microcontroller is an intelligent device and hence will be responsible for the decision making.
2. It will receive the data from the computer via wireless link.
3. It will then decode the data and look for the respective command.
4. That command will be sent to the output port .
