I'm trying to gain a deeper understanding of DC stepper motor because I'm using them for an arduino project.
I was wondering about why the common lead of unipolar stepper motors is usually (always?) connected to the high level voltage instead of ground.
Connecting it to ground should be the most logical thing to do, however, it is not the case. Of course, both cases should work fine for the motor, it just changes the controlling sequence, so that's not a big thing. But is there some advantages, some hidden motives to connect it to the high level voltage?
For reference: I'm using a 28byj-48 stepper motor (5 wires)
