[Andy] needed a cheap Internet connection between a data-gathering Arduino and his home server. An Ethernet shield would suffice, but he couldn’t run CAT5 to the Arduino’s location. Wir… ...

Arduino have taken the tiny wraps off of the official ethernet shield for their open-source prototyping platform, which adds network connectivity to the device. Based… ...

In that spirit, [Doug Jackson] shows you how to conserve the expensive Arduino board and Ethernet shield by building your own Arduino Ethernet module.

"Below are a couple of sketches for Arduino Ethernet: the first can be used to share sensor data with Pachube and grab remote sensor data, so you can effectively have both "local" and "remote ...

There is also a “Cloud Flash” feature to program networked-enabled devices like the Arduino Ethernet or Arduino & Ethernet Shield.
