MoonModules/WLED is a fork from Aircoookie/WLED which contains latest merge of v0.14 of WLED with additional features.
This fork is created by members of the Atuline/WLED team to make development against v0.14 possible while still preserving Atuline/WLED v0.13 as a stable and supported version. The Atuline/WLED fork is also called WLED SR (Sound Reactive).
