Virtuabotixrtch | Arduino Library

Check your wiring! The DS1302 is sensitive to loose jumper wires.

This is almost always because you have not removed or commented out the myRTC.setDS1302Time() function from your code. The DS1302 has its own backup battery. Your sketch should not set the time on every power-up. Use the setDS1302Time function once to set the correct time, then comment it out, re-upload the sketch, and the module will maintain the time from its backup battery.

You can find and install the library manually via the GitHub repository by downloading the ZIP and adding it through the (Sketch > Include Library > Add .ZIP Library). Some users on community forums also suggest using alternative libraries like RTClib by NeiroN or Makuna’s RTC library if they encounter compilation errors with the original Virtuabotix version. Keeping time with DS1302: real-time clock on Arduino virtuabotixrtch arduino library

While not as extensive as other libraries, the VirtuabotixRTC library offers all the essential features needed for basic timekeeping:

The VirtuabotixRTC library is a testament to the idea that sometimes, simpler is better. While the Arduino ecosystem has evolved, this library remains a robust and elegant solution for projects that require a real-time clock. Its intuitive "set it and forget it" functions and the direct variable access for time components lower the barrier to entry for beginners, while its lean nature makes it a reliable workhorse in more complex automation or data logging projects.

The library is perfect for hobbyist projects using the DS1302 RTC module. It's lightweight, easy to use, and requires only 3 digital pins. Remember to always call updateTime() before reading time variables, and set the initial time using setDS1302Time() only once.

Note: While pins 6, 7, and 8 are commonly used in textbook examples, the library allows you to utilize almost any digital pins on your Arduino board. Library Installation The DS1302 has its own backup battery

The DS1302 module is a low-power clock/calendar chip, commonly found as a small breakout board with five pins: VCC, GND, CLK, DAT, and RST. This is the module that the VirtuabotixRTC library is designed to communicate with, and mixing it with other RTC chips (like a DS1307) will not work.

// Create an RTC object virtuabotixRTC myRTC(PIN_CLK, PIN_DAT, PIN_RST);
