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…
