Hi.
It's my first time using an stepper with the controller ULN2003.
If search a lot of information about it and I finally done my project but the stepper doesn't changes its direction.
Has anyone and idea of why?
(Extra info: When I put negative values to change the direction it continues going as normal).

Thanks for the help and have a nice day.

You missed posting necessary information.

My crystal ball tells me you should flip the two middle pin numbers in the code, like

stepper(STEPS, 8, 9, 10, 11);
to
stepper(STEPS, 8, 10, 9, 11);

I think you should open a feer store.
