Just in time for Halloween, here is my new Halloween Fun 2019 Sketch and video which includes my new CD77_Flicker function which is based on fantastic code by u/locuester of FastLED Reddit (see sketch for link to u/locuester’s code).

Here is a video of the sketch on YouTube:

It will soon to be in my living room window as a pair on these pipes using the FastLED mirroring strips technique.

This sketch was run on a 5 ft strip of NeoPixels in a PEX pipe with a Teensy 3.2. The sketch was compiled using the Arduino 1.8.10 IDE, the Teensyduino 1.48 and windows 10 along with the latest version of the FastLED library.
