Sleeping Beauty; Low Power, RTC's, and Sleeping Processors. - A guided walkthrough

As our production of open source devices with a variety of sensors continues to roll out, it is of the utmost importance to try and make these devices as power efficient as possible in order to conserve battery life. The solution is simple, using a variety of adafruit and SparkFun libraries such a LowPower.h, RTClib and a custom RTClibExtended. However, the problem at hand is the compatibility and settle discrepancies between the processors we are using and how they interface with these libraries. This post will serve as a walkthrough on how to work with these power saving libraries with the latest 32u4 and M0 processor boards as well as integrating this logic into Arduino UNO projects.
