Does anyone have a schematic on a PWM or control board that will tell a motor to run so far then stop, and be able to be reversed, then run so far and stop?
Hope i said that right lol.
Basically i need to make a motor push something so far then stop. Then when down button is pressed it comes back so far then stops.

Any help would be appreciated. Instead of me searching for days, one of you I am sure would have the answer faster.
