Beginner question everyone.
I have set up 5 or 6 straight lines in x lights as outlines on my house. The first straight line is vertical and then the next one is horizontal, then vertical and so on....
I’m wondering, if I did a sequence that had a wave that lights up the pixels from top to bottom, how does x lights know the horizontal lights are horizontal. I’m concerned the lights would light up from left to right?
