The NeoPixel displays a rainbow cycle!
This example builds on the previous example.
First, you import the same three modules and libraries. In addition to those, you
import
colorwheel
The NeoPixel hardware setup and brightness setting are the same.
Next, you have the
cycle. It expects a

delay
color wheel to create a rainbow of colors.
Inside the loop, you call the rainbow helper with a 0.2 second delay, by including
