Very Cheap Arduino Nano & RC522 RFID module based UID reader for authentication/identification
- Arduino Nano v3.0
- Wires
- RC522 RFID Module
In order to use RC522 module you will need SPI library and MFRC522 library you can download it from the following links https://github.com/miguelbalboa/rfid
In the Arduino IDE go to “Sketch → Include Library →” and select “Add .ZIP Library…” then chose the downloaded files to add them into your Arduino IDE.
