Automatic Door Lock System Project

Index terms microcontroller stepper motor bluetooth device password.

Automatic door lock system project. The automatic door lock system circuit diagram using an arduino is shown below. This circuit is mainly used for an interfacing of rfid reader with an arduino. 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. This is a simple project made with arduino uno r3.

Because of this problem i decided to make my ow. This project can be enhanced by connecting an lcd display to display the outputs. 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.

This automatic password based lock system will give user more secure and low cost way of locking unlocking system. The aim is to control a door lock without keys but using a smart phone instead. In this project we will make a digital door lock system with keypad using arduino uno. Both passwords can be changed as and when required.

Smart bt door lock simple arduino project showcase by arun. 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.
