This is the most frequently used function. Calling updateTime() inside your loop() refreshes the library's internal variables with the current time from the DS1302 chip. After calling it, you can access the time components.

#include // Creation of the RTC Object (CLK, DAT, RST) virtuabotixRTC myRTC(6, 7, 8); void setup() Serial.begin(9600); // Set time once: (sec, min, hr, day of week, day of month, month, year) // Day of week: 1=Sunday, 2=Monday, etc. myRTC.setDS1302Time(00, 30, 15, 2, 21, 4, 2026); void loop() // Update time variables from the chip myRTC.updateTime(); // Access individual elements Serial.print("Current Time: "); Serial.print(myRTC.hours); Serial.print(":"); Serial.print(myRTC.minutes); Serial.println(); delay(1000); Use code with caution.

The VirtuabotixRTC.h Arduino library is a popular and widely-used library for working with Real-Time Clocks (RTCs) in Arduino projects. Developed by Virtuabotix, a well-known brand in the electronics industry, this library provides an easy-to-use interface for communicating with RTC modules, enabling accurate time-keeping and date-tracking capabilities in Arduino-based projects.

// --- Different ways to display time ---

When you first power a new DS1302 chip, the time is random. You must set it. You should only run the setting code once and then comment it out. Writing to the RTC every loop wears out the memory. #include // Creation of the RTC Object (CLK,

: 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.

To set the date and time, you can use the setDateTime() method, which takes a DateTime object as an argument. Here is an example:

int lastSecond = 0; void loop() myRTC.updateTime(); if (myRTC.second != lastSecond) lastSecond = myRTC.second; // Print or process time only once per second Serial.println(myRTC.second); Developed by Virtuabotix, a well-known brand in the
