VirtuabotixRTC.h Arduino Library — Overview and Guide

The VirtuabotixRTC.h library is a lightweight Arduino library for interfacing with common real-time clock (RTC) modules based on the DS1307 and similar I²C RTC chips. It provides simple functions to set and read the current time and date, and to convert between raw RTC register values and human-readable formats suitable for embedded projects.

Date Variables

  • myRTC.dayofmonth (1-31)
  • myRTC.month (1-12)
  • myRTC.year (0-99, represents 2000-2099)
  • myRTC.dayofweek (1-7, where 1 = Monday, 7 = Sunday)

Tip 3: Battery Backup Trick

If your DS1302 is running slow, check the voltage on pin 3.3V. Some modules have a diode that drops voltage. Powering the VCC pin with 5V and the backup battery with 3V can cause issues. Ensure the main power matches the chip's spec sheet. virtuabotixrtc.h arduino library

Error: virtuabotixRTC.h: No such file or directory: 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.
