Automatic door lock system project.

Index terms microcontroller stepper motor bluetooth device password. The automatic door lock system circuit diagram using an arduino is shown below. Password based door lock system using 8051 microcontroller circuit design uses five major components a microcontroller an l293d motor driver a dc motor a 4 4 matrix keypad and a 16 2 lcd. Because of this problem i decided to make my ow.

This is a simple project made with arduino uno r3. First we have to enter password for blue tooth connection and second is for unlocking the door in application. It will open your door only when the right password is entered and it will start beeping when a wrong password is entered. In this project we will make a digital door lock system with keypad using arduino uno.

I know how irritating doorbell sounds whenever it rings we have to hold our work and getup to open the door. This controller requires a supply voltage of 5v dc. The aim is to control a door lock without keys but using a smart phone instead. Both passwords can be changed as and when required.

The circuit of this project uses three separate parts namely a reader a controller and door lock. As thefts are increasing day by day security is becoming a major concern nowadays. This project can be enhanced by connecting an lcd display to display the outputs.
