Virtuabotixrtch Arduino Library |verified| Jun 2026

If you see a frozen date (e.g., 45/25/2165 ), check your wiring. The DS1302 is sensitive to loose connections on the RST or CLK pins.

The VirtuabotixRTCH Arduino Library offers several features that make it easy to integrate the RTC module with Arduino boards: If you see a frozen date (e

unsigned long getUnixTime(VirtuabotixRTC &rtc) rtc.updateTime(); // Use a helper function (requires <TimeLib.h>) return makeTime(rtc); // This requires conversion logic While modern projects often use the DS3231 for

The library is a popular, lightweight choice for interfacing Arduino with the DS1302 Real-Time Clock (RTC) module . While modern projects often use the DS3231 for better accuracy, the virtuabotix library remains a staple for beginners due to its simplicity in setting and retrieving time. Key Features

The VirtuabotixRTC library is an Arduino library created to interface with the . It handles the unique 3-wire communication protocol, allowing you to set, read, and write time/date data to the chip.
