!free!: Virtuabotixrtc.h Arduino Library

The virtuabotixRTC.h library is a specialized Arduino library used primarily for interfacing with the DS1302 Real-Time Clock (RTC) module. It provides a straightforward way to set and retrieve time data (seconds, minutes, hours, day, month, year) using a three-wire serial interface. Core Functions & Usage

3. Time Resets to 2000/01/01 Every Power Cycle

• Cause: The backup battery is dead or missing.
• Fix: Measure the battery voltage. It should be >2.5V. Replace if necessary.

// 1. Raw integers (Best for logic) Serial.print("Raw Data: "); Serial.print(myRTC.hours); // 24-hour format Serial.print(":"); Serial.print(myRTC.minutes); Serial.print(":"); Serial.println(myRTC.seconds); virtuabotixrtc.h arduino library

This simplicity allows even beginners to build functional time-aware devices. The virtuabotixRTC

void printDigits(int digits) 
  if(digits < 10) Serial.print("0");
  Serial.print(digits);
delay(60000); // Wait 1 minute between readings Cause:  The backup battery is dead or missing
