I am brand new to Arduino and so I am still trying to find my feet but I had a challenge to read an RFID tag (NFC) using a RC522 reader and so I downloaded the GitHub example from miguelbalboa/rfid.
The program starts 100% but, upon presenting the card, show "time out" error messages.
I have searched everywhere and there is a lot of references to this problem but no real satisfactory solutions that work in my instance....
Firmware Version: 0x92 = v2.0

Can anyone please help... Graham (newbie), Durban
