From the Forums: Retro Multimeter Neopixel Project #neopixel
danowar shared a retro multimeter neopixel project in progress on the Adafruit Forums:
…This project involves several different banks of NeoPixels — there are 4 groups of 4 NeoPixels (2 of these groups are the 8mm standalone traditional LED type of form factor, and the other 2 groups are the same but are 5mm instead, which should make no difference from a programming standpoint). Another ‘group’ is a NeoPixel Jewel, which has 7 pixels. Another is a single, standalone NeoPixel, and the last group is an 80-pixel matrix (consisting of an 8×8 pixel matrix with a 1×8 pixel stick on each side). Each group is on its own PWM pin, with the exception of the single standalone pixel, which is on digital pin 2 (this one is effectively just a power light).
Everything is all wired up and it all works just fine; what I’m trying to figure out now is how to write a sketch that can talk to each of them…
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
