  • I think I understand the switch and LED matrix. But if I understand correctly, if I turn on Red (for example) on the top row, then red will be on for all 4 columns on the top row. In other words, I can’t have the top row be red, red, blue, blue. Instead it would be red, red, purple, purple. Is this correct?

No public wish lists :(
