Thanks for the edited picture which will help newbies to set their 8825 up.
One remark: the logic power supply from Arduino to RESET/SLEEP is actually not needed to adjust the current limit.
That said I am thinking of adding a post about what is essential to get the motor run and how to set up microstepping of the A4988 and DRV8825.
@Robin2:
I am fine with sharing this knowledge, admitting that I only concentrated existing information in one place - but at the time when I started with stepper motors and drivers I wished it would have been found in one place.
