Automatic door locking system using bluetooth module.
Shilpi banerjee has implemented an automatic password based door lock system.
This system works on pre decided password concept.
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.
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.
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.
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.
This allows the user to lock and unlock a door from inside or outside a house with a bluetooth device available.
With the use of wireless bluetooth connection the system installation in more easy way.
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.
