Abstract: Through the use of the Espressif Systems32(ESP32) microcontroller's embedded Global Positioning System (GPS) Neo 6m module, DS3231 RTC, Network time protocol(NTP) Pool Server, and Organic ...

Displays time (HH:MM:SS), date (DD.MM or DD.MM.YYYY), and temperature (TT°C). Setup mode for adjusting time/date via three buttons (Mode, Plus, Minus). 8x8 font (0-9 ...

This repo can be used to setup RTC clock (DS3231). The sketch includes a simple AT based serial communication protocol that can be used to set the time. The solution can be embedded into existing ...

You can buy all kinds of conventional clocks that have hands and numbers for easy reading. Or, like [Fabio Ricci], you could build yourself something a little more esoteric, like this neat shadow ...
