Automatic Door Lock System Project

The automatic door lock system circuit diagram using an arduino is shown below.

Automatic door lock system project.

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. Smart bt door lock simple arduino project showcase by arun. This project can be enhanced by connecting an lcd display to display the outputs.

I know how irritating doorbell sounds whenever it rings we have to hold our work and getup to open the door. It will open your door only when the right password is entered and it will start beeping when a wrong password is entered. First we have to enter password for blue tooth connection and second is for unlocking the door in application. Index terms microcontroller stepper motor bluetooth device password.

Here an at89c52 microcontroller is used and it is an 8 bit controller. 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. The circuit of this project uses three separate parts namely a reader a controller and door lock. In this project we will make a digital door lock system with keypad using arduino uno.

As thefts are increasing day by day security is becoming a major concern nowadays. This automatic password based lock system will give user more secure and low cost way of locking unlocking system. This is a simple project made with arduino uno r3.
