Sound Reactive
A 7 band coaxial color organ based on the MSGEQ7 audio analyzer chip.
Roulette
Simple Roulette is a single spinner with 8 pockets.
Super roulette is an 8 spinner wheel using all the LED positions as pockets.
Horse Race
An eight lane horse race.
Sparkle
A simple random sparkling color effect. The knobs adjust the sparkle persistence and spawn rate.
Time Tunnel
Another display, not so random though; use the knobs to adjust the display.
Two Player Skill Contest
Two players compete to claim the most LED rings
by hitting the button when the LED is on the starting line.
Etch-A-Sketch
This is a tool that helps with the code development to create "images".
Use the knobs to select a pixel location and color.
The image can be saved using the serial monitor diagnostic console.
This is how the menu triangle images were created.
