RTC clock with NTP updates using just Uno R4 WiFi board

I used info from https://www.hackster.io/mdraber/digital-clock-with-arduino-uno-rev4-wifi-s-rtc-an-led-matrix-484d2e and also from https://github.com/eremef/aur4_clock but I changed the number style (redefined some numbers/characters) and added seconds beat.

You need to change the lines no. 23 and 24 with your credentials (name and password of your WiFi network), also change in line no. 202 number 43200000 with 3600000 (NTP update at every hours not at 12 hours).
