Complete Arduino RFID tutorial using RC522 module. Learn wiring, programming, and build practical projects like door locks. Code examples included.

The project implements Arduino UNO as a base controller. It utilized SIM808 for GSM, GPS and GPRS connectivity. The project also implements RFID module RC522 for Mayfair card integration. The project ...

The RC522 RFID reader is interfaced with Arduino using SPI protocol. The following circuit connections are made for interfacing the RFID reader with Arduino UNO.

In this tutorial, we are going to interface RDM6300 RFID Reader Module with Arduino Nano. The RDM6300 RFID Reader is one type of RFID module with a 125 kHz frequency.

Therefore, an effort was made to design a tool for “identification of impedance changes in metals using an Arduino Uno-based RFID RC522” which is relatively inexpensive and easy to carry.
