The MFRC522 RFID reader is connected to the Arduino Uno with VCC (3.3V) to 3.3V, GND to GND, RST to digital pin 7, SDA (SS) to digital pin 10, MOSI to pin 11, MISO to pin 12, and SCK to pin 13. The ...
Note that the digital pin used for the LCD backlight must support PWM. Currently pin 6 is configured, which is valid for all current Arduino boards. Pull-up resistors on SDA/SCL are required.
