Web Controlled Arduino LED

Web Controlled Arduino LED

This instructable shows you how to build a Web-enabled tri-color LED based on an Arduino and the WIZnet Ethernet shield, controllable from any Web browser . Check the live demo at http://try.yaler.net/~arduino/led Because the LED is exposed through a simple RESTful web service running on the Arduino color changes can also be triggered by Pachube

Charlieplexed row of LED lights for the Arduino

Charlieplexed row of LED lights, for the Arduino

I tried to keep the project simple, but that didn’t work very well. The soldering is complex, I wouldn’t recommend this as a first time soldering project.
