Per lo shield WiFly e' stata effettuata la patch descritta qui
Per la connessione del lettore Rfid si usano i seguenti pin
VCC : 3.3V
GND :
MOSI: Pin 11 / ICSP-4
MISO: Pin 12 / ICSP-1
SCK: Pin 13 / ISCP-3
SS: Pin 10
RST: Pin 9
MISO: Pin 12 / ICSP-1
SCK: Pin 13 / ISCP-3
SS: Pin 10
RST: Pin 9
da notare che vista la presenza dello shield il PIN 3.3V risulta coperto per cui e' stato necessario mettere una patch piegando il piedino in modo da poter appoggiare lo shield. In realta' si potrebbe rubare la corrente saldando un contatto direttamente sullo shield
Lo sketch inizializza il lettore Rfid e la WiFly. Successivamente nel loop attende che venga passato il tag Rfid, lo legge ed invia il codice allo script in Php sul server
