Господа. Скетч взят из этой темы. https://www.thingiverse.com/thing:2381829

Мотор вращается в полшага со скоростью один оборот в минуту.

Мне нужно получить один оборот в 6 минут, то есть в 6 раз медленнее, но любые попытки сделать delay больше или меньше заставляют двигатель вращаться быстрее. Что я делаю не так? Вот скетч
