Virtuabotixrtch Arduino Library Guide

#include <VirtuabotixRTC.h> // Pin definition for Uno/Nano // (SDA, SCL) VirtuabotixRTC myRTC(A4, A5); This is your most important function. It reads the current time from the RTC chip and stores it in the myRTC object's variables.

Note: The Virtuabotix library automatically uses the Wire library under the hood, so you don't need to define pins unless using software I2C. virtuabotixrtch arduino library
