From the Forums: Animations Mapped on Six SK6812 LED Concentric Rings
Thanks to Forums user Disciple for not only sharing this project and video but also the code to easily recreate it yourself – read more on the forums!
An online supplier sold me a disc of SK6812 LEDs on concentric rings for my dad. He wants to create a window display, so I have some Halloween ideas.
The rings are 6, from a single pixel to 32, in increasing sizes. They’re joined by breakaway bridges, but I’m keeping them united. They’re easily wired to count from the center outward, and an Uno or Pro Trinket drives them readily. I created a mapping that allows the Adafruit_NeoMatrix library to perform Adafruit_GFX functions in a recognizable manner. If anyone is working with a similar disc, I’m sharing my sketch.
The radar screen sweeps out a color wheel rainbow
The jack-o-lantern light has a random-walk glimmer
The eye of “Sour-one” twitches left and right in a random-walk direction
The skull’s jaw chatters
Not pictured is a marquee crawl message, “Happy Halloween!”
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
