Hi, I am writing to the forum to promote Aaron Averill’s NeoSprite library. It was very useful for me, a novice, to quickly produce animation for a homemade NeoPixel strip matrix. Please see: https://youtu.be/KBtatQ6hKQU
It is written for CircuitPython. The examples come with button press code to switch between animations, as demoed in my movie. You can also switch button state to true to play a folder of animations end to end as if it were one long movie. For my 21 x 8 pixel matrix, powered by the Adafruit Feather M4 Express ATSAMD51, I was able to make animations 180 frames long or more, 8 bit, but also could play a folder of animation as if it were a longer movie.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
