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 ...

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 ...

In this tutorial we are going to design a system to read the ID of RFID cards. RFID stands for Radio Frequency Identification. Each card has a unique ID embedded in it. These systems have many ...

This project uses an RFID module (RC522) to create an access control system with Arduino. The system checks RFID tags against a stored authorized UID and provides visual and audio feedback based on ...

This RFID Based Access Control System is built around Arduino UNO board, RFID reader module, solenoid lock and a few other components. RFID is a non-contact, automatic identification technology that ...

RFID (short for Radio Frequency Identification) tagging is an ID system that uses electromagnetic waves in radio frequency to transfer data. A simple RFID system consists of just two components: the ...
