An easy to use real time clock library for Arduino, it was in the public domain, but not on GitHub, so I uploaded it. Problem with code for Arduino using an RTC - Programming

If you are following a specific tutorial that uses this library, it works perfectly fine for basic timekeeping. However, for new projects, many experts recommend moving to the RTClib by NeiroN RtcDS1302 by Makuna virtuabotixrtc.h arduino library

// Print the date and time Serial.print("Date: "); Serial.print(myRTC.month); Serial.print("/"); Serial.print(myRTC.dayofmonth); Serial.print("/"); Serial.print(myRTC.year); Serial.print(" - Time: "); Serial.print(myRTC.hour); Serial.print(":"); Serial.print(myRTC.minute); Serial.print(":"); Serial.println(myRTC.second); An easy to use real time clock library

When you first get an RTC module, it has random garbage data. You must set the current time. The key concept is that you set the time , upload the sketch, and then comment out the set functions in subsequent uploads. You must set the current time

The library was originally in the public domain and is now primarily maintained on platforms like GitHub (chrisfryer78/ArduinoRTClibrary) . It is not always available in the built-in Arduino Library Manager, so manual installation via is often required.
