Virtuabotixrtc.h Arduino | Library

To initialize the library, you must create an object instance and define the pins connected to the module:

Unlike your PC or smartphone, the standard Arduino (Uno, Mega, Nano) does not have a built-in battery-backed clock. As soon as you unplug the USB cable, its internal counter resets to zero. This is where Real-Time Clock (RTC) modules come in. virtuabotixrtc.h arduino library

: The DS1302 chip used by this library is known to have significant drift (sometimes 20+ seconds per day) compared to higher-precision chips like the DS3231 . To initialize the library, you must create an
