A simple Arduino project using the MFRC522 RFID module to read and display RFID tag UIDs on the Serial Monitor. This project uses an RFID-RC522 module with Arduino to read RFID tags and display the ...

This project demonstrates how to use an RFID RC522 module with an Arduino to authenticate RFID cards. The system turns on a green LED if an authorized RFID card is scanned and turns on a red LED and ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...
