Andy from the UK was looking to build a simple proof of concept project which would integrate an Arduino and ENC28J60 based ethernet shield (or a Nanode) to connect with his Pachube account to control an RGB LED. [via]
This article describes a simple application to demonstrate the ENC28J60 EtherShield library. It can be run on a plain Arduino or clone and an ethernet shield based on the ENC28J60 ethernet chip (Note: This is not the same as the official ethernet shield). An alternative is to use the Nanode (see the wiki site at Hackspace) which combines the arduino and the EtherShield into a single compatible board. It also demonstrates the network capability of the board and the control functionality included in the Pachube dashboard application.
