Duino Starter Kit for Arduino This code implements a Larson Scanner with adjustable color and speed. During the last couple years you can get some LED lights that change color and make interesting patterns. Adafruit 16 WS2812 LED NeoPixel Ring so you will need to swap. Python code causes faded neopixel colors where it should be bright I'm using a microbit connected to a neopixel with 32(8x4) lights, and in the code I've made, where I've specified the code to be blue(or any color), the result is a very weak and faded color from. It looks like the version of the neopixel module is an old version before the 4 colour LED's were supported. published by the Free Software Foundation, either.
