Using Arduino to render patterns on a 16x16 LED Matrix
I wanted a night light to very slowly rotate through a variety of great patterns. So I have it rotate through 9 different patterns, one per hour. Most of the patterns were borrowed from other places. Many were tweaked by me.

My hardware includes a Adafruit Feather M0 Basic Proto. (I recommend a M4 express instead)

And a prop maker
https://www.adafruit.com/product/3988 - Allows me to use the accelerometer and maybe up-voltages the data out.
I added a button to cycle through different modes, and holding it enters demo mode.
