Hello friends! In the previous tutorial, we controlled the direction of a DC motor in Proteus . Now we will work with a stepper motor, where rotation depends on applying an ordered sequence to the windings. We will begin with the original six-wire simulation, inspect the sequence manually, and then explain how a microcontroller and driver can generate it. The original screenshots use Logic State sources to make individual winding states visible. They are useful for understanding the sequence, but they are not a physical driver circuit. We will preserve the images and add the missing distinction between simulated logic sources, microcontroller outputs, and the winding-current path. By the end, you should understand unipolar and bipolar wiring, wave drive and half stepping, direction reversa ...
