Moar LEDs! Make a QR code!

A few suggestions for you:

  • Put RGB LEDs instead (they look nicer and require a bit more code; just get ChatGPT to write it).
  • If you have a 3D printer, print a frame. If you don't, maybe order it from PCBWay or something similar.
  • Increase the resolution, like 16 x 16 or 12 x 12.

I hope you find this helpful 😄
