hi all,
its been a while since i last posted on here i have been so busy, i even moved to New Zealand in that time!!!
i have a question, i have been researching for a long time on how to accomplish this but i always hit a brick wall.
here is my problem.
im trying to do something very simple, i want to turn a motor (servo/dc etc) with a multi turn input device like a multi turn pot or an encoder, if i move the controller 234.5 degrees clockwise, i want the motor to folow my movement and stop when i stop.
i looked into this, and what i found was PID controll, but most of the controllers were hooked up to pc's, i want to build a standalone device that does almost exactly what a r/c servo and a contoller does except instead of 90 degrees of movememt i want 1800 degrees.
ive looked into having ten turn pots sitting on the shaft o fthe motor producing feed back or using opt encoder (to bulky) best would be the hall sensor!?
please help thanks
simon
