Detailed Description

Shows how to use a circular noise generator to have a continuous noise effect on a ring of LEDs.

Author: Zach Vorhies

This sketch is fully compatible with the FastLED web compiler. To use it do the following:

Install Fastled: pip install fastled
cd into this examples page.
Run the FastLED web compiler at root: fastled
When the compiler is done a web page will open.
