Hi, I have a website that is hosted with "Hostgator" and I would like to use it with the ethernet sheild and mega2560 to switch on or off a light and was wondering if anyone has any tips to help me along. I have the Arduino live http://220.127.116.11:89 so it's port forwarded, and I have the example Sketch working so it shows the Analogue port data. How do I write a simple sketch that works with my website rather than Twitter to interface with my Arduino and ethernet shield? Is it RSS related, so a simple .xml file? Alternately, I have a Micro SD card plugged into the Ethernet shield it's 8gb in size, is there a way to store HTML, XML and PHP documents on it and just call them when they are needed?
Thanks for your help and time. Rob
