INTRODUCTION As technology is advancing so houses are also getting smarter. Modern houses are gradually shifting from conventional switches to centralized control system, involving remote controlled switches. In order to achieve this, a Bluetooth module is interfaced to the Arduino board at the receiver end while on the transmitter end, a free android application on the cell phone (ArduDroid or DIY Smarthome).

BLOCK DIAGRAM

WORKING When the toggle buttons on the application are pressed, corresponding bluetooth signals are sent from android phone to the bluetooth module that hooked up to the arduino. When it identifies that signal, then the arduino activates the relay hooked up to its digital pin by passing 5V through it. Thus the relay is switched ON and the corresponding appliance connected to the relay is turned ON as well.

APPLICATION Using this circuit we can control lights, air conditioning, door locks,etc all from the smartphone. Remote controlled home automation system provides a most modern solution with smart phones

ADVANTAGES Home automation systems can reduce energy consumption, increase security and make a home more comfortable. DISADVANTAGES The primary disadvantages are the costs, the disruption in installing a wired system, and the potential complexity.
