Servos have many uses and can be a lot of fun to play around with. Something that can be heaps of fun is taking control of up to six servos over the internet! Just imagine the possibilities.
This process is made really simple using the Teleduino sketch for your ethernet enabled Arduino. Haven't heard of Teleduino? That's cool, you may want to take a look at Arduino Control via a Web Service with Teleduino
to get yourself started. It's designed to be quick and easy for rapid development.
This tutorial will guide you through the process of attaching a servo to your Arduino, and provide some example Teleduino API call to:
Define a servo instance
Set the position of a servo
