So I’m stuck with this one, and the hint in the back doesn’t really help, I had guessed so myself already. But then, what is the next step?
Spoiler
The arrows can’t link directly to a specific LED segment, because the number of arrows don’t match the 7 segments. Does a white arrow mean the segment goes white? Does that mean a skipped segment is black? What about the black arrows? And why are they combined with white arrows? Some arrows seem to point to the same segment again, does that undo the previous arrow, or am I looking at it wrong?

What am I missing? Thanks!
