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.

void loop() myRTC.updateTime();

int alarmHour = 7; int alarmMinute = 0;

Enter the library. For many hobbyists, this is the go-to, lightweight solution for interfacing with the popular DS1302 and DS1307 RTC chips. In this comprehensive guide, we will dissect everything you need to know about this library—from installation and basic wiring to advanced coding and troubleshooting. What is the VirtuabotixRTC Library? The VirtuabotixRTC.h library is an Arduino library written to simplify communication with low-cost RTC modules, specifically the DS1302 (3-wire interface) and the DS1307 (I2C interface).
