The circuit of this project uses three separate parts namely a reader a controller and door lock.
Rfid based automatic door locking system project.
Arduino rfid door lock hardware project setup.
When we see sophisticated door management system s the price tag struck immediately along with the utility of course.
It s very important to authenticate the user before entering into a secure space and rfid provide this solution.
This project can be enhanced by connecting an lcd display to display the outputs.
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.
So in this project we are going to make an iot based door lock system using nodemcu solenoid lock and adafruit io.
An rfid based door lock with cyclops as display.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
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.
The automatic door lock system circuit diagram using an arduino is shown below.
Coolest door lock ever project tutorial by vivek gupta.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
This automatic password based lock system will give user more secure way of locking unlocking system.
The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag.
A digital door locking system is also implemented and governed by rfid reader which authenticate and validate the user and open the door automatically.
In countries like india such automatic systems are not cheap by any yardstick.
First the user combination will be compared with prerecorded password which are stored in the system memory.
We store a set of rfid card data in our system say 3 or 10 rfid card data.
This rfid door lock can be made easily at your home and you can install it in any door.
User can go for certain number of wrong combinations before the system will be temporarily disabled.
An rfid based door lock is based on some simple concepts.
You have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room.
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.
