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!”
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
