The door lock circuit is using the electromagnetic principle so for the project that will be builds.
Automatic door lock system project report.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
If entered password is correct then door is open by motor which is used to rotate the handle of the door lock.
Smart bt door lock simple arduino.
In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on.
The aim is to control a door lock without keys but using a smart phone instead.
Download the project report.
This simple fingerprint door unlock project using arduino can be very useful for door security forensics crime investigation personal identification attendance system and much more.
We surveyed many smart doors locking system.
This project can be enhanced by connecting an lcd display to display the outputs.
Projects on password based door lock system using microcontroller april 21 2014 by tarun agarwal 40 comments the basic requirement of security can be achieved by designing electrical or mechanical locks that are designed with one or a few keys but for locking a big area many locks are required.
Then for the output it haves push button emergency break glass and the door lock circuit.
Next for the controller it uses the xp m1000x as a controller.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
2 introduction to the project automatic door with visitor counter automatic doors are doors which open automatically when approached by someone rather than needing to be opened manually with a door handle or bar.
In case the user forgets the both passwords this.
The system works using keypad to enter a password to the system.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
System also includes extra features like adding new users and changing old password etc 1.
The project design a rfid based passive keyless entry for automobile door lock application is successfully implemented using rfid communication module with atmel 8051 at89c51 programmed based on embedded system technology.
The circuit of this project uses three separate parts namely a reader a controller and door lock.
The concept of the electromagnetic principle will be use in the project.
The automatic door lock system circuit diagram using an arduino is shown below.
This is a simple project made with arduino uno r3.
It increases the security level to prevent an unauthorized unlocking done by attacker.
