Virtuabotixrtch Arduino Library

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

If you are building a battery-powered logger, you cannot call updateTime() every second. Instead, wake up the microcontroller, update once, read the time, log data, and go back to sleep. The RTC keeps running on its own battery. virtuabotixrtch arduino library

When choosing an RTC library, you often have to decide between this library and the more popular RTClib by Adafruit. The following table outlines the key differences to help you make an informed choice. Note: The Virtuabotix library automatically uses the Wire

A typical wiring configuration is shown in the table below: wake up the microcontroller
