The automatic door lock system circuit diagram using an arduino is shown below.
Rfid based automatic door locking system project.
The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag.
This project can be enhanced by connecting an lcd display to display the outputs.
So in this project we are going to make an iot based door lock system using nodemcu solenoid lock and adafruit io.
A digital door locking system is also implemented and governed by rfid reader which authenticate and validate the user and open the door automatically.
Arduino rfid door lock hardware project setup.
It also keeps the record of check in and check out of the user.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
This rfid door lock can be made easily at your home and you can install it in any door.
Coolest door lock ever project tutorial by vivek gupta.
First the user combination will be compared with prerecorded password which are stored in the system memory.
An rfid based door lock with cyclops as display.
The circuit of this project uses three separate parts namely a reader a controller and door lock.
This automatic password based lock system will give user more secure way of locking unlocking system.
Rfid based door automatic management system arduino rfid module rc522 simple project arduino will read rfid tag and display to the serial monitor.
Here nodemcu will act as the main controller and connect the user to the door lock system using the internet.
User can go for certain number of wrong combinations before the system will be temporarily disabled.
This allows the user to lock unlock his home s door lock by using a smartphone from anywhere in the world.
You have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room.
When the person with the right rfid card compatible to data preloaded in our program system come and swipes his rfid tag access will be granted.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
An rfid based door lock is based on some simple concepts.
You are given a card and you just need to put it in front of a rfid reader box and the lock gets unlocked with a beep and a blink of led.
In countries like india such automatic systems are not cheap by any yardstick.
We store a set of rfid card data in our system say 3 or 10 rfid card data.
So we decided to test a simple and cheap prototype to see if such a robust system could be developed using the tool of our choice arduino uno.
