Smart Cheap Voice Home Automation with Arduino - Turn your lights on with your Phone !

DIY Home automation !

Good home for the cheap !
Tired having to get out of bed and walk all the way to the switchboard to switch off the wifi/lights? What if we just had to say "lights off" while lying comfy in our bed. This arduino based project makes it possible !

Instructable : www.instructables.com/id/Voice-Activated-Arduino-B…

Parts required : An Arduino, A bluetooth module, a 5V relay board, some male-to-female jumper cables, and ofcourse, an Android phone and an appliance !

I am using an Arduino Uno, HC-05 bluetooth module and a 12V relay board, however, the Arduino only has 5V and 3.3v output and hence is not enough to control a 12v relay.
