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.
Automatic door locking system using bluetooth module.
Proposed work is to send a signal to door from a tablet or mobile devices by using bluetooth system.
With the wireless bluetooth connection in microcontroller permits the system installation in more easy way.
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.
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.
The ideal purpose of the work is if the door.
With the use of wireless bluetooth connection the system installation in more easy way.
