RFID with Arduino
Introduction (How it Works)
Mifare RC522 is the highly integrated RFID card reader which works on non-contact 13.56mhz communication, is a low power consumption, low cost, and compact size read and write chip, is the best choice in the development of smart meters and portable hand-held devices.
For this module you will need:
Connect the sensor as described below.
|Pin||Wiring to Arduino Uno|
On your PC, Download and install the Arduino IDE from here.
- Download the RFID library here created by Miguel Balboa
- Unzip the RFID library
- Install the RFID library in your Arduino IDE
- Restart your Arduino IDE
Now, in the Arduino IDE, Go to File —> Examples –> MFRC522 —> dumpinfo
Connect your Arduino with a USB cable to your PC and upload the code to your Arduino UNO. Open up the serial monitor from tools —> serial monitor and now as soon an RFID it would show up on the serial monitor. Voila! The project is now complete.
