Edit:
This post has now been updated to use the newer and currently maintained Arduino etherCard libraries. A new sketch had also been added to provide an example of how to use this new library with your ethernet module. If you are using V1.0 or above of the Arduino software environment, we recommend using this new library and sketch.

This is an example of how to use the Hobby Components ENC28J60 Ethernet
module (HCARDU0028).
To use this sketch you will need to download and install the EthernetCard library
available at the following location:
https://github.com/jcw/ethercard
Alternatively, a known working snapshot can be downloaded from the microduino section
of our support forum:
http://forum.hobbycomponents.com/
This example program will serve a basic webpage at the ip address specified below.
As an example of content, the webpage contains the current status of the analogue input
pins.

This is an example of how to use the HobbyComponents Arduino module shield
(HCARDU0028). For this example to work you will need to download the appropriate
libraries available at:
http://forum.hobbycomponents.com/viewtopic.php?f=25&t=6
Unzip the libraries and copy them to your Arduino libraries folder.
This program will serve a basic webpage at the ip address specified below which will
allow you change the state of 4 relays. This program is intended to work with arduino
relay modules such as the HobbyComponents 4 channel relay module (HCARDU0025).
