Shilpi banerjee has implemented an automatic password based door lock system.
Automatic door locking system using bluetooth module.
It increases the security level to prevent an unauthorized access done by the attacker.
With the wireless bluetooth connection in microcontroller permits the system installation in more easy way.
Proposed work is to send a signal to door from a tablet or mobile devices by using bluetooth system.
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.
This system works on pre decided password concept.
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 ideal purpose of the work is if the door.
