This remix does not modify the Shiura clock, which looks perfect, but proposes a method for using an ESP32-C3-super-mini instead of the RP2040 zero

Although the original sketch delivers the expected functionnality, using Wifi on C3 provides additional features

The provided sketch enables WiFi in HC5, with different way for using it :

• Using Smartconfig (and the ESPtouch phone application) to setup wifi credential initially (default mode)
• Clock time is synchronised on Internet
• Using Standard Wifi by entering credentials in the sketch
• Clock time is also synchronised on Internet
• Making the clock a Wifi access point ; in this case, the clock time is synchronised to the browser one
• This is useful on location with no Internet access
