Coolest door lock ever project tutorial by vivek gupta.
Rfid based automatic door locking system project.
Here nodemcu will act as the main controller and connect the user to the door lock system using the internet.
The automatic door lock system circuit diagram using an arduino is shown below.
In countries like india such automatic systems are not cheap by any yardstick.
This project can be enhanced by connecting an lcd display to display the outputs.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
So in this project we are going to make an iot based door lock system using nodemcu solenoid lock and adafruit io.
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.
First the user combination will be compared with prerecorded password which are stored in the system memory.
You have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room.
This allows the user to lock unlock his home s door lock by using a smartphone from anywhere in the world.
A digital door locking system is also implemented and governed by rfid reader which authenticate and validate the user and open the door automatically.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
User can go for certain number of wrong combinations before the system will be temporarily disabled.
This automatic password based lock system will give user more secure way of locking unlocking system.
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.
The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag.
It also keeps the record of check in and check out of the user.
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.
We store a set of rfid card data in our system say 3 or 10 rfid card data.

An rfid based door lock with cyclops as display.
Rfid based door automatic management system arduino rfid module rc522 simple project arduino will read rfid tag and display to the serial monitor.
This rfid door lock can be made easily at your home and you can install it in any door.
An rfid based door lock is based on some simple concepts.
It s very important to authenticate the user before entering into a secure space and rfid provide this solution.
