I've been playing with the ENC28J60 for a few months and even thought it isn't as easy to work with as the official EtherShield it is still a great (really cheap) bit of kit)
One of my goals was to control the Arduino Pins from a web page. Kind of home automation type scenario.
This is the first step in that direction.
I have a XAMP web server installed on my netbook with delivers a PHP web page to the browser.
The web page gives me the options to turn on or off 2 LEDs on pins 2 and 4 of the Arduino.
When I press a button the web page is called again and in the background the web server does an fopen() call to the Arduino with the requested action.
By using fopen() the actual command sent to the Arduino is not seen by the user.
The below video shows it working and in the description on Youtube there is a link to my blog with further details and the code for the web server and the Arduino.
All feedback appreciated.
