Lock Your Door Automatically

Everyone at some part of their life wanted that no one should enter their room or garage in their absence. This project will guide you how to this using a controller, a RFID reader and a little bit of control mechanisms. The components used were basic Arduino 168 chip, along with a RFID reader and the electric door lock. Initially you might have to install the ready-made electric door lock and test with a battery of suitable power to ensure that the door lock in installed correctly or not.

Generally while installing, one would want that no current flows through the electronic door lock when the door is in locked state. The reader is placed on the outside of the door and is separated from the controller on the inside so that no one can interfere with the security by breaking Reader and trying to short circuit the reader. The controller receives serial data from the Reader and controls the RGB led and the Door lock.
