Creazione di post automatici su Facebook con RFID (6)

Riprendendo il filone degli esperimenti precedenti in questo caso il lettore Rfid e' legato ad una Arduino che si occupa del carico di lavoro per l'interfaccia Web
Le connessioni per il lettore RFID sono

MOSI: Pin 11 / ICSP-4
MISO: Pin 12 / ICSP-1
SCK: Pin 13 / ISCP-3
SS: Pin 6 
RST: Pin 7

La scheda Arduino ha ovviamente montato lo Shield Ethernet
