/*
AUR4 Clock
RTC clock using NTP server to sync time
Created using the Arduino Uno R4 Wifi example code - RTC_NTPSync, initially created by Sebastian Romero @sebromero
Instructions:
1. Change the WiFi credentials in the arduino_secrets.h file to match your WiFi network.
2. Set the orientation using the #define ORIENTATION 0 or 1
3. Set timezone offset hours using the #define TIMEZONE_OFFSET_HOURS according to your localization
