// Create an RTC object virtuabotixRTC myRTC(PIN_CLK, PIN_DAT, PIN_RST);
Checking for a specific minute rollover is trivial:
To use the library, you typically download it as a ZIP from repositories like chrisfryer78's GitHub and install it via the Arduino IDE Example Implementation ArduinoRTClibrary/virtuabotixRTC.h at master - GitHub
That night, a storm knocked out the power. Usually, this meant Eli would wake up to a confused greenhouse and a flooded floor. But when the lights flickered back on, the DS1302—powered by its tiny coin-cell heart—whispered the exact second to the Arduino. The virtuabotixRTC library translated that heartbeat into data, and the system resumed exactly where it left off.
Once the library is installed and your DS1302 is wired up, you can start using it. The code below demonstrates how to set the time for the first time and then read it back over the Serial Monitor.
The library correctly handles the DS1307’s square wave output and battery switchover detection via myRTC.isPowerOnReset() .
// Define the connection pins: CLK, DAT, RST // MyRTC(ClockPin, DataPin, ResetPin) VirtuabotixRTC myRTC(6, 7, 8);
If you're building a new project, invest your time in learning RTClib . If you're working with an existing codebase, this guide should provide you with all the information you need to understand, install, and use the virtuabotixRTC library.
The functions are intuitive, making it great for beginners who might be overwhelmed by the more complex bit-math usually required to read/write to RTC chips.
Arduino Uno, Nano, Mega, or compatible clone. RTC Module: A DS1302 Real-Time Clock module. Jumper Wires: To connect the module to the Arduino. Breadboard: Optional, for easy prototyping.
Before diving into the code, you will need to pair your Arduino with an RTC module. The library natively supports:
