This tutorial talks about how to make an RFID door lock system using Arduino. Also, this tutorial covers how to make a door lock system step by step at minimal cost, so that everyone can do it easily. The RFID module is mainly used for this project. Also, the lock is designed to operate automatically using a servo motor and a manual door lock. Using the knowledge in this tutorial, you can easily design a door lock system for your home doors.
How this door lock system works
When power ON this door lock, the servo motor activates and pushes the door lock forward. Also displayed as “Welcome, put your card” on the LCD. Then when the RFID tag is moved closer to the RFID reader, it is scanned. In that case, it is displayed as “scanning” on the LCD. Then, if the RFID tag is correct, the servo motor is activated and the door lock is pulled back. The LCD shows “Door is Open”. When the RFID tag is moved closer to the RFID reader again, if it gets the correct tag, the servo motor will push the lock forward. Displays “Door is locked” on LCD. If a wrong RFID tag is used according to the program, it will be displayed as “Wrong card” on the LCD.
