// V 1.3.6 - 19.02.2024
//
// *********************************************
//
// TOBERS MULTIDISPLAY, based on the fantastic Parola Library by majic Designs,
// turns your LED-Matrix display into a widely configurable and customizable message center.
// It shows current time & date, weather forecasts, current news, custom messages
// and - ESP32 only - songs currently playing on Spotify.
// Configuration and settings are made via web interface.

// ****************************************************************
//
// Credits:
// - Special thanks to Marco Colli (MajicDesigns) for his libraries, the excellent documentation and the support via arduino forum.
// - Special thanks to Benoit Blanchon for his great Arduino Json Library and his friendly support.
// - Local language concept and some parts of weather functions inspired by ericBcreator -> https://www.hackster.io/ericBcreator/1024-led-matrix-wifi-message-board-with-menu-web-interface-1b2666
// - SPIFFS administration taken and adopted from the great Arduino ESP website https://fipsok.de/ (Jens Fleischer)
// - HTML background pattern graphic by Henry Daubrez, taken from http://thepatternlibrary.com/
// - Thanks to the many, many other programmers and enthusiasts whose work and helpfulness enabled me to realize such a project
