Virtuabotixrtch Arduino Library

Sets the time on the DS1302 chip. Note: dayofweek (1=Sunday, 7=Saturday) is usually ignored by the DS1302 but required for compatibility.

Because standard Arduino boards lack a built-in battery-backed clock, relying on them for timekeeping means the clock will reset every time the power cycles. RTC modules like the DS1302, DS1307, and DS3231 solve this problem perfectly, and the library makes communicating with these chips incredibly straightforward. What is an RTC and Why Do You Need It?

virtuabotixRTC library is a widely used Arduino library specifically designed to interface with the DS1302 Real-Time Clock (RTC)

While there are multiple RTC libraries available in the Arduino ecosystem, stands out for a few major reasons:

The entire library avoids malloc() and new . Every variable is statically allocated. For hardcore embedded developers, this means predictable memory usage and zero fragmentation risk—even after months of runtime.
