Hi, I'm trying to finish my school project but I'm stuck with my code, can someone help me please? thank you.

My code is looping form 9-0, thats our countdown goal but I need it to stop at zero before looping to the next digit(tube) but its turning off. Can someone help me on what can I do? thank you :slight_smile:

What did you try? What happened when you did that? And for understanding, what was the reasoning behind it?
