This Instructable extends Arduino Ethernet controller to control a set of up to 6 relays, but that's not the neat bit. The neat bit is that there is a web based state machine in the AtMega chip so that the relays will operate in whatever sequence with whatever timing you want - all by themselves.
This allows you to have a set of relays connected to the end of a piece of Ethernet cable that can be accessed from a web browser anywhere from your house.
