This is a very simple project for Arduino beginners. In this project we have I have used Arduino UNO, HC-05 Bluetooth Module and a SG90 Servo Motor to implement a Blutooth controlled door locking system. Via bluetooth terminal you can control this motor to lock/unlock your door. If you send the right password through the bluetooth terminal then the motor will unlock the door.
