RTC clock with NTP updates using just Uno R4 WiFi board (2)

I updated the previuos RTC clock with NTP updates based just a Arduino Uno R4 Wifi board (see https://www.hackster.io/user0035382/rtc-clock-with-ntp-updates-using-just-uno-r4-wifi-board-a5790a ), just sketch was improved to be more easy to understand.

The

The text was rotated to 180 degree (but display can be as in previous article if variable rotate = 0, because 0 -> original and 1 -> 180 degree rotate).

For WiFi credential are in lines no. 14 and 15.

Also, for update time from NTP server at every hours it need to change the 43200000 = 12 x 60 x 60 x1000s with 3600000 = 1 x 60 x 60 x 1000ms.
