The goal is to open a door by using a specific tag that functions as an access badge.
How to make a door lock rfuid.
What you need to make your own arduino based rfid lock.
You can watch the following video or read the written tutorial below for more details.
Arduino uno or other buy here arduino power supply buy here rc522 rfid sensor buy here breadboard jumpers for testing buy here micro servo buy here 2 x leds buy here 2 x 220ω resistors buy here 3d printer filament optional for lock this one used how to make your rfid door lock.
If the wrong tag is scanned the door will stay closed and set off a buzzer.
This project guide will detail the steps to create an rfid radio frequency identification door lock system using an arduino mega 2560.
In this tutorial we will make the door lock with an arduino based rfid door lock.
