/*
The original code was taken from the following project:
https://hackaday.io/project/190207-esp8266-word-clock-on-16x16-led-matrix
Some adaptions and extensions were made by PhysTechAG - see Git history.

IMPORTANT NOTE: We had some struggles with the recent versions of the
NeoPixel library (v1.12.2) on the ESP32. It made the
device constantly reset. v1.11.0 was the last version
that worked for us.
