![]() ![]() ![]() RC522 is a Multi-communication RFID Module for Arduino and Microcontrollers. Build a door security system using RFID RC522 reader module.interface the RC522 reader module with Arduino UNO.know the introduction about RC522 RFID reader module (features and pinout).Additionally, after looking through the example sketches we will also build our own door security system with the help of the RC522 RFID reader module.īy the end of this tutorial you will be able to: ![]() We will use Arduino UNO with it and show you some simple example sketches that will demonstrate how to use the reader module. The RFID reader module that we will look upon is known as RC522. from supermarkets for fast checkouts to well-maintained security systems for banks/jails/server rooms. Due to their fast, accurate and secure nature, they are widely used with microcontrollers in various fields e.g. These RFID reader modules are very handy in today’s fast-paced world. In this user guide, we will look at an interesting way to use Radio Frequency Identification (RFID) technology via RFID reader module. ![]()
