This occurs if you leave the setDS1302Time() command active in your code. Once the time is initially saved to the module's battery-backed memory, that line should be deleted or commented out.

delay( // Wait one second Use code with caution. Copied to clipboard Tips for Success Installation: Download the ArduinoRTClibrary and install it via Sketch > Include Library > Add .ZIP Library in the Arduino IDE. Prevent Resets:

The DS1302 RTC offers a practical way to add accurate timekeeping to Arduino projects. The virtuabotixRTC.h library makes it a very approachable option. Have you used this library, or are you planning to use it in a specific project?

The library is lightweight and focused solely on DS1302 functionality, making it ideal for microcontrollers with limited memory. Hardware Wiring

This means the library is not installed in your Arduino IDE. Because it is a legacy public domain library, it is not always found in the official library manager. You must download the ZIP folder from a trusted repository like GitHub's ArduinoRTClibrary and click Sketch > Include Library > Add .ZIP Library in the IDE.

Download the virtuabotixRTC library source folder (usually available as a ZIP file on GitHub). Open your Arduino IDE.

line and upload again. Otherwise, the clock will reset to that specific time every time the Arduino restarts. Pin Compatibility:

from the RTC chip and stores it in library variables. Example Code Implementation chrisfryer78/ArduinoRTClibrary - GitHub

This example shows you how to initialize the RTC, set the time (once), and print the time to the Serial Monitor.

: Manages seconds, minutes, and hours (including 24-hour or AM/PM formats).

// Your wiring: (CLK, DAT, RST) virtuabotixRTC myRTC(4, 3, 2);

void loop() // This function updates the variables inside the object with current RTC data myRTC.updateTime();

Choose VirtuabotixRTC for its uncompromising simplicity and low resource usage when your project specifically uses a DS1302 RTC module. Choose RTClib for larger, more complex projects where flexibility and advanced features are a priority.

In the realm of embedded electronics, keeping track of accurate time is a common yet critical challenge. For many hobbyists and professional developers, Arduino projects that involve data logging, automated control systems, or timed events require a reliable source of real-world date and time information. This is where the VirtuabotixRTC library comes into play. The virtuabotixRTC.h Arduino library is a lightweight, easy-to-use solution designed to interface with , providing a straightforward way to read, set, and manage time data in your Arduino projects.

The virtuabotixRTC.h library is an Arduino library designed specifically to make reading and writing time data from popular RTC modules—most notably the —incredibly easy. Unlike more complex libraries, virtuabotixRTC.h handles the heavy lifting of converting raw register data from the RTC chip into human-readable integers (seconds, minutes, hours, days, months, years) instantly. Why Choose This Library? Simplicity: Highly intuitive syntax for beginners.
