Virtuabotixrtc.h Arduino Library ((link))
The virtuabotixRTC.h library is a popular, lightweight Arduino library designed to interface with Real-Time Clock (RTC) modules, most notably the DS1302. It allows developers to easily read and write time and date data, making it a staple for projects like digital clocks, data loggers, and automated timers.
| DS1302 Module | Arduino Uno | | :--- | :--- | | VCC | 5V | | GND | GND | | CLK | Digital Pin 7 | | DAT | Digital Pin 6 | | RST | Digital Pin 5 |

This is the most crucial function in the library. Before you can read any time data, you must call myRTC.updateTime() . This command fetches the latest time values from the DS1302 chip and stores them in the myRTC object's variables. You should call this function at the beginning of your loop() or whenever you need a fresh timestamp. The virtuabotixRTC
