I have a ULN2003 stepper driver module that I received in a starter kit with a unipolar stepper. I am having some issues getting it running (it seems to vibrate as if its trying to move but not actually move).
Anyway, after going over the wiring a few times to make sure I'd not made any silly mistakes I've noticed that in the documentation there are conflicting drawings showing how it's wired to the Arduino UNO board.
One image shows Pin IN1 on the driver to Pin 8 on the Uno..... then 2-9, 3-10, 4-11. Like this
Whilst another shows the opposite; Pin IN1 on the driver to Pin 11 on the Uno.... then 2-10, 3-9, 4-8. I don't have a link to this as it's on the Elegoo instruction DVD that I got with the kit.
Has anybody used this driver and can you confirm the correct order? I understand to some extent that as long as you write the code accordingly then it doesn't matter but as I'm de-bugging I want to be 100% sure it's wired correctly. The library code states stepper is on pins 8,9,10,11 (in that order).
Thank you in advance, Paul
