OOOHHHHH MightyAni GOOODDD of Codes hear my pray !
I wanted to know if it's possible to make this effect on an adafruit neopixel 60
https://www.youtube.com/watch?v=OR33T0X-W7k the code is this one:
/*
Reboot Ghostbusters Proton Pack (lights only)
NeoPixel Driver for Trinket Pro
Authors: Dustin Westaby, Danielle Gormley
Date: August 31, 2016
Use a 24 LED neopixel ring, or loop a strip.
Animation is to match the Proton Pack from 2016 movie
Use potentiometer for a color selection knob.

and if it's possible to when i push a button to have the same flash as you.
I am really sorry to ask sooo much things but I am completely lost ! For exemple I don't know why "colors" seems to be defined differently. In a code , you have 3 values for a color (mix of R,G,B = the color than you want) and in other codes red is define by a code like "0xff0000". It's disturbing for beginners
Thank you
