I want to control a 5v relay from the arduino using ethernet. I have an Arduino Duemilanove with a wiznet chip ethernet shield mounted on top of it. How could I control a relay from a php webserver?

Ethernet controlled LED HELP?

Zoomkat, I tried your sketch, but whenever I clicked "Off" the relay turned off then turned back on. Any idea why it does this?
