The automatic door lock system circuit diagram using an arduino is shown below.
Automatic door lock system project.
This automatic password based lock system will give user more secure and low cost way of locking unlocking system.
First we have to enter password for blue tooth connection and second is for unlocking the door in application.
This is a simple project made with arduino uno r3.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
Index terms microcontroller stepper motor bluetooth device password.
In this project we will make a digital door lock system with keypad using arduino uno.
It will open your door only when the right password is entered and it will start beeping when a wrong password is entered.
The circuit of this project uses three separate parts namely a reader a controller and door lock.
The aim is to control a door lock without keys but using a smart phone instead.
This controller requires a supply voltage of 5v dc.
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.

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.
Both passwords can be changed as and when required.
