Stepper Motor Controller with H-Bridge

A lot of precision controlled elements in the world are moved using stepper motors. Stepper motors are pretty complicated when compared to simple DC motors. This complexity is where their precision originates. And in order control something that is complex, you need a controller that is also complex: an H-bridge circuit board.

Drawing Machine, Part I

For my final project, I’ve decided to continue with the idea of a drawing machine, but with a slightly different…
