RFID-RC522 : Unable to get it working

Hello!

I am trying to get working my RFID-RC522 with Arduino but it just won't work. For reference, this is what I have :

I have used the code of the following page : Learning/MFRC522.

The connections are the following :

  • SDA -> Pin 10
  • SCK -> Pin 13
  • MOSI -> Pin 11
  • MISO -> Pin 12
  • IRQ -> Not connected
  • GND -> GND
  • RST -> Pin 9
  • 3.3V -> 3.3V

For the library I use : miguelbalboa/rfid
And I use a Arduino Uno...

Thanks!

but it just won't work.

Something happens. You need to share the Serial data you are seeing now, and, probably, add more, so you KNOW what is happening.
