ah well they do say assumption is the mother of all screw ups. I assumed because the description said it was a servo it would act like a servo. So what i have is more of a stepper motor, right?
to get this to work as desired i would need to feed back the position of the needle, right? Could I do this with a encoder wheel? http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1257038219
I am tempted to get a standard servo for an easy life but i really want a range of motion more than 180. A standard servo that operates between 0-360deg would be ideal.
