Re: Gear tooth sensors - Forward or backward?

If you can't be sure that the motor will be moving in the same direction it's commanded, there's no good way to do what you want in software. The best thing I can think of is to use two gear tooth sensors on the same gear, mounted so that they give a quadrature signal just like a rotary encoder would.

Or just add a rotary encoder and be done with it.
