Introduction

Have you ever wanted a certain color for a NeoPixel project and had trouble figuring out which RGB or HSV values to enter? You can use web colors to try and get specific colors but you never know how it will look in real life until you load up your code and see it in action. This project allows you to use potentiometers to adjust the red, green and blue values individually in real time to fine tune NeoPixel colors and to see exactly how RGB and HSV values from the code work in practice.
