delay(1000); // Wait 1 second before reading again
For DS1302 users, the main alternative is the library by Henning Karlsen (often named DS1302.h ). Karlsen’s library is more feature-complete, offering alarm support and better error checking. However, it is also larger and more complex. The VirtuabotixRTC library is often preferred for very small projects or when code simplicity trumps feature richness.

void loop() myRTC.updateTime(); int hour = myRTC.hours; int minute = myRTC.minutes;
The library is a widely-used Arduino resource specifically designed to interface with the DS1302 Real-Time Clock (RTC) chip . While many RTC libraries favor I2C-based chips like the DS3231 or DS1307, the Virtuabotix library remains a staple for the DS1302 because it simplifies the module's unique three-wire serial communication protocol.

: Once the time is set, you should comment out this line and re-upload the sketch to prevent the clock from resetting every time the Arduino restarts.
