Read RFID Tag Using RFID-RC522 And Arduino

We use RFID system for our toll, home security, industry and many more in our country. But do we know how it works? 🧐🧐

In this tutorial, I’ll share with you on how to display on I2C OLED using Arduino. The video will cover on :

  1. Installing library for RFID-RC522.
  2. Reading the RFID Tag with example provided.
  3. Use the data read by the RFID-RC522.

HARDWARE PREPARATION

This tutorial use :

  1. Maker UNO
  2. Mifare RC522 RFID Kit
  3. USB Micro B Cable
  4. Jumper Wires
  5. LED 2x
  6. Resistor 220 Ohm 2x

You can make the hardware connection based on the diagram and table below.
