Hello,

Have you looked into using a stepper motor driver chip with your MCU?

Look up a stepper motor driver chip made by a company called Allegro
on digikey.

They make drivers for both bipolar and unipolar steppers. Their chips
can provide resolutions per turn higher than what is rated on the
stepper motor by creating 'microsteps' between each step. Changing a
bit will forward/reverse direction on the motor. Look for the
appropriate chip to drive the load you intend to use.

This is just a suggestion.
