This code will be available in arduino ide after installing the rfid library.
Rfid activated door lock arduino.
Reading data from an rfid tag.
In arduino project in this project tutorial you will use the multiple mfrc522 to control a solenoid lock and three leds.
After having the circuit ready go to file examples mfrc522 dumpinfo and upload the code.
Arduino controls the process.
Rfid uses electromagnetic fields to identify and track tags attached to an object.
Rfid and keypad based door lock using arduino to open the door the user will have to first scan the right tag and then he will have to enter the correct password.
Then open the serial monitor.
Whereas the feeder controls access to a food bowl the door controls access to an entire room.
Connect a led to digital output 13 and verify that everything is working.
You can load as many rfid tags as you d like onto the arduino and add or remove tags to provide more or fewer people with access.
Some methods and techniques are borrowed from my previous project the rfid cat feeder.
The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe.
The first step to building a rfid door lock with a basic arduino is to bread board out a basic working arduino.
It features a custom made antenna large enough to function as a gate which makes it easy for the animal to activate and quite reliable.
You should see something like the figure below.
Hey friends in this video i will show you how to make rfid lock system visit my website to download codes and circuit diagrams https www viralsciencecrea.
When someone swipes the corresponding rfid card in front of the reader the reader lets the arduino know that the correct card has been read and to then operate the servo unlocking and locking the door.
This is a really easy rfid door lock mechanism which is based on the arduino uno and the rc522 rfid sensor which allows you to use rfid tags or cards to lock and unlock a door drawer or cupboard.
Most arduino pre flashed atmega 168 chips come with the default blink program pre installed.
