This is a simple serial controller for multiple servos based on the Arduino. (my first instructable too :) )
Most of the work in this came from getting the software to talk with the arduino and making a protocol for the data to be passed over. As for the hardware aspect all that I used was two servos (Parallax standard servo here
.) A Sparkfun
and an Arduino
Duemilanove with ATMEGA328, but most of these parts can be substituted with similar items.
I thought up this project as part of a RC system, but setting up the communication took a lot of time. If anyone has any improvements, ideas, or bugs please feel free to comment.
EDIT: I wrote this awhile ago, just got to publishing it recently.
