Tutorial: How to use RFID H019 UNO R3 Start Kit

The RFID H019 learning kit is ideal for anyone who wants to start working with RFID technology using Arduino. This kit allows you to create simple access or monitoring systems.

What you need

• Arduino UNO R3
• USB A-B cable
• RFID H019 learning kit

Steps

1. Connect the Arduino UNO to the computer via the USB cable.
2. Download and install the MFRC522 library for Arduino from the GitHub repository.
3. Open an existing sketch that uses the MFRC522 library or create a new empty sketch.
4. Connect the pins of the RFID module to your Arduino UNO as specified in the datasheet.
5. Upload the sketch to your Arduino UNO.
6. Start the serial monitor to see the information transmitted by the RFID tag.

Example code

/* Configurazione base dello sketch */
#include <MFRC522.h>

#define SS_PIN 10
#define RST_PIN 9
MFRC522 mfrc522(SS_PIN, RST_PIN); // Instanzia l'oggetto MFRC522 con i pin specifici.
void setup() {
  Serial.begin(9600);
  mfrc522.PCD_Init();
}

void loop() {
  if ( !mfrc522.PICC_IsNewCardPresent()) return;
  if ( !mfrc522.PICC_ReadCardSerial()) return;
  Serial.print("UID tag: ");
  printHex(mfrc522.uid.uidByte, mfrc522.uid.size);
}
void printHex(byte *buffer, byte bufferSize) {
  for (byte i = 0; i < bufferSize; i++) {
    Serial.print(buffer[i] < 0x10 ? "0" : ");
    Serial.print(buffer[i], HEX);
  }
}

Mini project

Create an access system that turns on a light bulb when a specific RFID tag is detected.

Common mistakes

• Make sure the pins of the RFID module are correctly connected to the Arduino.
• Check that the MFRC522 library is installed and configured correctly.
• Ensure that the RFID tag works properly before uploading the sketch to Arduino.

Recommended accessories

• LED light bulb
• LED resistor
• Prototype kit
