I’m new to Particle and as my first project I have been trying to get an RFID card reader to work with a Particle Argon
I have followed the guide and copied the code listed in: https://www.hackster.io/ingo-lohs/rfid-kit-particle-photon-a-first-introduction-9544f1
However I cannot seem to get the Console to say anything other than “Card NOT detected” when testing with both a keychain and card reader.
Im using the following Pin combinations:
#define SS_PIN A2
#define RST_PIN D2
#define MOSI_PIN D3
#define MISO_PIN D4
#define SCK_PIN D5
3V3 to 3V3
GND to GND.
Any help is greatly appreciated, thanks!
