Automatic Door Locking System Using Bluetooth Module

With the use of wireless bluetooth connection the system installation in more easy way.

Automatic door locking system using bluetooth module.

Shilpi banerjee has implemented an automatic password based door lock system. 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. Proposed work is to send a signal to door from a tablet or mobile devices by using bluetooth system. The system has been successfully designed and aimed to control the door condition using an android bluetooth enabled phone and bluetooth modules via bluetooth hc 05.

It increases the security level to prevent an unauthorized access done by the attacker. This system works on pre decided password concept. 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. 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.

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.
