I'm having trouble with getting this motor to work and could use some help/guidance, please. I have a micro gear motor with encoder which I got from ServoCity (https://www.servocity.com/90-rpm-micro-gear-motor-w-encoder) and am trying to use it for a project which will require some fairly accurate movement. I used a servo before, but it was too loud and too inaccurate for my needs, and burned out after a couple of years.
I haven't yet gotten to the encoder part of the my control (although I intend to use that to mark "top center", eventually) - so right now I'm using an Arduino and a voltage step-up board. I can make the motor turn by setting the Enable pin on the step-up board to high - however I'm unable to fine-tune the control. It seems to do a full-spin and stop, no matter how briefly I make the pin high. Attempting to do this with PWM doesn't seem to help or produce anything.
In my research I haven't found any code specific to this motor, so I don't know if this is a complete limitation of this motor, or if I'm doing something wrong in my approach.
Any help/code/advice you could give would be much appreciated.
