Step 1: Connecting the RC522 RFID Module. First, let's connect the RC522 RFID module to the Arduino. The RC522 module communicates via SPI (Serial Peripheral . Step 1: Connecting the RC522 RFID Module. First, let's connect the RC522 RFID module to the Arduino. The RC522 module communicates via SPI (Serial Peripheral Interface). Here are the connections you need to make: RFID RC522 pinout. The IRQ pin is not connected to anything. 3.3V: Connect to 3.3V on the Arduino. So, that’s all about how to use the PN532 NFC RFID module with the Arduino and how to use all the three interfaces or modes UART, I2C, and SPI. In my upcoming tutorial, I will use the same PN532 RFID module with the Nodemcu ESP8266 and Google Spreadsheet.In this tutorial, we are going to learn how to use RFID/NFC with Arduino. The RFID/NFC system includes two components: reader and tag. There are two popular RFID/NFC readers: RC522 and PN532 RFID/NFC reader. This tutorial focuses on RC522 RFID/NFC reader.
Using I2C to Communicate with RFID Reader. As mentioned above, it is possible to use I2C instead of SPI in communicating with the RC522 RFID reader module. To enable I2C, we must cut the connection of the trace on the board to pin 1 on the IC. This can be done by drilling a hole on a board as shown by user Renate-USB of the Arduino community.
The module allows the developers to interface it with any other SPI, I2C, and UART based microcontrollers. The RC522 module works on 13.56 MHz frequency and it can act as a reader and write for UID/RFID cards.In this beginners guide, you will learn how to connect an RFID reader module to an Arduino Uno and read tag information from RFID cards and tags. We will go over the components needed, how to wire up the circuit, example Arduino code to interface with the reader, and testing procedures. This RFID reader can be interfaced with a controller/computer using UART, SPI, and I2C protocols. The RFID reader/writer IC in MFRC522 uses a 13.56 MHz radio frequency for its operation. MFRC522 RC522 can read/write RFID . In this post we will go over how to use the RC522 RFID Module with Arduino. We’ll focus on basics, module pins, how to connect to Arduino, programming in Arduino IDE, and testing. The main focus will be around reading an RFID tag’s UID (Unique ID).
For today’s tutorials, we will use the RC522 RFID reader to obtain the UID of tags placed near it and to create a simple prototype of an RFID based door lock system. The RC522 RFID reader is a low cost, highly integrated, 13.56 MHz contactless communication enabled reader module. The Mifare MFRC522 is an RFID card reader that incorporates SPI bus communication, I2C bus, and UART, making it easy to connect to Arduino. The MFRC522 supports Mifare S50, Mifare S70, Mifare UltraLight, Mifare Pro, and Mifare Desfire cards. Step 1: Connecting the RC522 RFID Module.
