Rfid Activated Door Lock Arduino

The mfrc522 uses radio frequence identification rfid.

Rfid activated door lock arduino.

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. Then open the serial monitor. After having the circuit ready go to file examples mfrc522 dumpinfo and upload the code.

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. 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. Reading data from an rfid tag. You should see something like the figure below.

Arduino controlled lock box with solenoid and rfid project tutorial by robotgeek projects team 10 461 views. The first step to building a rfid door lock with a basic arduino is to bread board out a basic working 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. In arduino project in this project tutorial you will use the multiple mfrc522 to control a solenoid lock and three leds.

This code will be available in arduino ide after installing the rfid library. Arduino controls the process. Most arduino pre flashed atmega 168 chips come with the default blink program pre installed. Rfid uses electromagnetic fields to identify and track tags attached to an object.

Connect a led to digital output 13 and verify that everything is working. 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. Whereas the feeder controls access to a food bowl the door controls access to an entire room. 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.
