Welcome! This guided tutorial will help you show a number on the LED screen!

Show a number on the LED screen! One digit will display at a time, scrolling from left to right.

But we also should pause before showing another number.

Keep displaying multiples of 7 such as 21 and 28, but don't forget to add pauses between the numbers!
