A credit card sized Ethernet Arduino compatable controller board

This project is my simple Arduino compatible controller that has embedded Ethernet, and the capacity to drive some extra I/O lines for projects, such as a Remote thermometer, a Remotely accessible Fridge controller, and a Remote Humidity sensor. I have to say from the start that I didn’t write all of the software, my mate Mikal did that - but this instructable is about making your own controller board!”
