We are pretty excited about this tutorial! We controlled a motor's speed and an LED over the web using:
Using the Arduino Ethernet: http://www.jayconsystems.com/product_detail.php?prod_id=172
Ardumoto V2 Shield: http://www.jayconsystems.com/product_detail.php?prod_id=114
There are many pages online offering to show you how to host a website from an Arduino Ethernet, and control the Arduino from that hosted website, but those mainly share the same method: sending a request by changing the website url address.
In this tutorial, I will be using the second available HTML method: sending a request by actually sending a DATA packet (Posting Data).
This is what the website looks like, which is used to control the motor and led.
If you would like to try, here is the write up and all the code, Enjoy!http://www.jayconsystems.com/forum/viewtopic.php?f=10&t=90
