Fireworks LED addition and modifying Arcade buttons

Last Updated or created 2026-01-07

I’ve given people on the street control over my Xmas/Fireworks lights last month. (This month it is going to be converted to an interactive game)

I saw some LED strip dividers on Aliexpress, next year it’s going to have a star on top.

Like this….

Another LED related project I started today is a Whack-A-Mole game with multiple levels.
For this I need to convert a simple arcade button to a programmable multicolor version.

From single white LED to multi color, programmable.

Using analog multiplexer for 16 digital inputs for a game

Using CD74HC4067

Only partly drawn ..

This will be for a multi level Whack-a-Mole.

  • Multi level
  • Multi player
  • Score display
  • Color coded
  • Bonus scores
  • Follow the color mode (like simon says)
  • …. more

Another game in the making is a Red Light – Green Light game.
Like in Squid Game.
This will use a lidar and a python script which detect movement using a camera.
