====
Arduino RFID Library for MFRC522
Read a card using a mfrc522 reader on your SPI interface on your Arduino
* Pin layout should be as follows (on Arduino Uno):
* MOSI: Pin 11 / ICSP-4
* MISO: Pin 12 / ICSP-1
* SCK: Pin 13 / ISCP-3
* SS: Pin 10 (Configurable)
* RST: Pin 9 (Configurable)

TODO:
Create Examples:
- Read more stuff than the serial number
- Write to a card
- Do some ethernet stuff (with an ethernet module)

* The circuit:
* LCD RS pin to digital pin (7)
* LCD Enable pin to digital pin (6)
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 3
* LCD D7 pin to digital pin 2
* LCD R/W pin to ground
* 10K resistor:
* ends to +5V and ground
* wiper to LCD VO pin (pin 3)
