Looking at this web page, i found a simple stepper motor driver circuit https://www.electronicshub.org/stepper-motor-driver-circuit/
The problem is, i just can't understand how it can work when the diodes are reversed. And even if they were not reversed, i still cannot see how any of the coils be energized when one of the pins on the CD4017 counter turns on.
At first i thought the circuit must be flawed until i saw the video showing it does work, with the reversed diodes. Video : https://www.youtube.com/watch?v=ejvTG90kA0k
