🔧 Features & Specifications
🔧 Library Setup & UID Reader Example
Install MFRC522 Library
Arduino IDE → Sketch → Include Library → Manage Libraries → Search MFRC522 by miguelbalboa → Install.
Wire to Arduino (SPI)
RC522 SDA→10, SCK→13, MOSI→11, MISO→12, GND→GND, RST→9, 3.3V→3.3V on Arduino Uno. For ESP32 use default SPI pins (SS=5, SCK=18, MOSI=23, MISO=19).
MFRC-522 Read Card UID Example
#include <SPI.h> #include <MFRC522.h> #define SS_PIN 10 // SDA pin #define RST_PIN 9 MFRC522 rfid(SS_PIN, RST_PIN); void setup() { Serial.begin(9600); SPI.begin(); rfid.PCD_Init(); Serial.println("✅ Scan your RFID card..."); } void loop() { if (!rfid.PICC_IsNewCardPresent()) return; if (!rfid.PICC_ReadCardSerial()) return; Serial.print("Card UID: "); for (byte i = 0; i < rfid.uid.size; i++) { Serial.print(rfid.uid.uidByte[i] < 0x10 ? " 0" : " "); Serial.print(rfid.uid.uidByte[i], HEX); } Serial.println(); rfid.PICC_HaltA(); }
Open Serial Monitor at 9600 baud. Tap the included card or fob to read its unique UID.
