Rfid uses electromagnetic fields to identify and track tags attached to an object.
Rfid activated door lock arduino.
The servo that controls the door is being controlled by the micro controller and the arduino is being told when to unlock and lock the door with the rfid reader.
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.
Whereas the feeder controls access to a food bowl the door controls access to an entire room.
Reading data from an rfid tag.
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.
Some methods and techniques are borrowed from my previous project the rfid cat feeder.
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.
The first step to building a rfid door lock with a basic arduino is to bread board out a basic working arduino.
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.
The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe.

Connect a led to digital output 13 and verify that everything is working.
The mfrc522 uses radio frequence identification rfid.
This code will be available in arduino ide after installing the rfid library.
After having the circuit ready go to file examples mfrc522 dumpinfo and upload the code.
Intermediate protip 2 hours 25 722 things used in this project.
You should see something like the figure below.
Then open the serial monitor.
Most arduino pre flashed atmega 168 chips come with the default blink program pre installed.
In arduino project in this project tutorial you will use the multiple mfrc522 to control a solenoid lock and three leds.
