1. Materials you need in this project.
2. I’m using a really tiny bipolar stepper motor which can be directly driven using arduino’s pin and stepper library.
3. Some screenshot of the steps.
4. Finished and test.
More details, psl check this video on Youtube:
To be honnest I don't understand the goal of your article and the link to the arduino. Is it "how to drive a stepper motor with an arduino" or "how to make a stepper motor" ?
