Arduino Code for the Ethernet Network Module ENC28J60 (Big):

The EtherCard library is the best library that makes this module work with Arduino, It can be downloaded by clicking here then you would have to add it to Arduino IDE

after that, you can upload this code which can make the Arduino web server with the help of the Ethernet Module
