Bluetooth Based Smart Door Lock System using Arduino



This project comprises of a smart door lock system that we created as a wonderful way to improve the home security system. We utilised Bluetooth devices to operate the door lock in the house using the Arduino IDE programme. The microcontroller is linked to a l293d driver IC, which is used to drive the DC Gearmotor forward (Open) and backward (Close), and the motor controls the door lock. In this approach, all data is controlled by a Bluetooth Android application. In that app, we transfer data over Bluetooth to control the house door lock, one of which is open and another which is closed. Nobody could hack the system since it was a closed-loop and very secure mechanism.
