Don't expect helpers to watch a tutorial. It doesn't tell what You have put together.
YouTube tutorials are not the best way to learn. See if there are written directions that go with the tutorial; otherwise, find some online, there are likely thousands.
You might be better off learning how to use steppers first. Do a library search on Stepper, pick one, install it, click the ... menu and pick a few samples to learn from.
Code or wiring error. Please read and follow the instructions in the "How to get the best out of this forum" post, linked at the head of every forum category.
