First we have to enter password for blue tooth connection and second is for unlocking the door in application.
Automatic door lock system project.
As thefts are increasing day by day security is becoming a major concern nowadays.
It will open your door only when the right password is entered and it will start beeping when a wrong password is entered.
I know how irritating doorbell sounds whenever it rings we have to hold our work and getup to open the door.
This is a simple project made with arduino uno r3.
The aim is to control a door lock without keys but using a smart phone instead.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
This project can be enhanced by connecting an lcd display to display the outputs.
The circuit of this project uses three separate parts namely a reader a controller and door lock.
Here an at89c52 microcontroller is used and it is an 8 bit controller.
The automatic door lock system circuit diagram using an arduino is shown below.
Both passwords can be changed as and when required.

In this project we will make a digital door lock system with keypad using arduino uno.
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.
