In this paper, we analyze the working principle of an arduino. These days many people try to use the arduino because it makes things easier due to the simplified version of C++ and the already made ...

It also uses a DS3231 real-time clock module as a backup, keeping accurate time even when a network connection is unavailable. Time is displayed via a 60-pixel ring of WS2812B addressable LEDs.
