  • Easy RFID MFRC522 Interfacing With Arduino Nano

    What I am doing is Connecting Pro Mini to Arduino UNO without IC to program Pro Mini. But the Pin Connection is done as per UNO, what will be change required ???

    Can Arduino pro mini be used to connect MFRC522Thank you for a detailed data on SPI

    Arduino RC522 RFID Door Unlock

    I have Arduino without IC to connect Pro Mini. I am trying to connect Pro Mini to RFIDbut is not responding . Code is simple #include #include #define SS_PIN 10#define RST_PIN 9MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance.void setup() { Serial.begin(9600); // Initiate a serial communication SPI.begin(); // Initiate SPI bus mfrc522.PCD_Init(); // Initiate MFRC522 Serial.println("Approximate your card to the reader..."); Serial.println();}void loop() { // Look for new cards if ( ! mfrc522.PICC_IsNewCardPresent()) { return; } // Select one of the cards if ( ! mfrc522.PICC_ReadCardSerial()) { return; } //Show UID on serial monitor Serial.print("UID tag :"); String content= ""; byte letter; for (byte i = 0;...
