MQTT DINo Realy Ethernet Board
Library reference :
MQTT Arduino library : https://github.com/knolleary/pubsubclient
Arduino UIP : https://github.com/ntruchsess/arduino_uip ( Used to drive ENC28j60 ethernet ic )
NB.
Need to remove every istance of Serial class, it appears to interfere with the normal program flow, i need more investigate . Maybe define a Software Serial could solve the problem . The code is only tested whit the KMTronic DINo realy board, but it should work with any board based on ENC28J60 .
