RFID Tag Detection with Arduino This project demonstrates how to detect RFID tags using an Arduino and an RFID-RC522 module. When an RFID tag is brought near the reader, the unique ID (UID) of the tag ...

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 ...

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 ...
