You'll need the following:

* esp32 boards: Arduino ESP32 Feather

* FastLED library

* WifiManagerTZ library (and its dependencies)

Apology
|

----------
|

|

I am no longer a C++ programmer.
|
||||
The structure of this code is awful.
|
||||
I'm sorry.
|
||||
I didn't feel like a 2-day refresher in a language I never use,
|
||||
for code nobody else is likely to ever compile.
