Rotating a simple DC motor really slowly (1 rotation per 2 hours)? Answered
This is to rotate a bike chain on a small cog.
After doing some research, I came across a component called a Pulse Width Modulator. Would this be suitable for turning a simple DC motor at 1 rotation per 12 hours(EDIT: I meant 1 rotation per 2 hours, not 1 every 12 hours)? Or, would it only get me to a certain point before I need to use gear ratios to achieve my ideal revs?
This really is a budget project so nothing too fancy.
