Automatic Door Locking System Using Bluetooth Module

The servo arm will be connected to the slider lock and will move to 0 degrees to lock the door and 60 degrees to unlock it using commands it gets from out bluetooth device.

Automatic door locking system using bluetooth module.

The ideal purpose of the work is if the door. It increases the security level to prevent an unauthorized access done by the attacker. The hardware design for door lock system is the combination of android smart phone as the task master bluetooth module as command agent arduino microcontroller as controller center data. With the use of wireless bluetooth connection the system installation in more easy way.

Wiring diagram lets start by wiring the servo to the arduino i would like to note that even though i m using the arduino nano the arduino uno will work just as well. Proposed work is to send a signal to door from a tablet or mobile devices by using bluetooth system. Shilpi banerjee has implemented an automatic password based door lock system. This allows the user to lock and unlock a door from inside or outside a house with a bluetooth device available.

This system works on pre decided password concept.
