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. This is where Real-Time Clock (RTC) modules come in

The virtuabotixrtc.h arduino library is a testament to the power of open-source hardware. It takes a potentially complex task—bit-banging a 3-wire serial protocol—and turns it into three lines of code. For beginners building their first digital clock, greenhouse timer, or automated feeder, this library is a perfect starting point. For beginners building their first digital clock, greenhouse
