Setup the RFID RC522 to Raspi like this:
- SDA connects to GPIO8 (Physical Pin 24)
- SCK connects to GPIO11 (Physical Pin 23)
- MOSI connects to GPIO10 (Physical Pin 19)
- MISO connects to GPIO9 (Physical Pin 21)
- GND connects to Breadboard Ground Rail. (20)
- RST connects to GPIO25 (Physical Pin 22)
- 3.3v connects to 3.3v (Physical Pin 1)
Enabled SPI (Interfaces)
pi@pi:~ $ sudo raspi-config
enabled SPI and reboot
