Version 1.0 Copyright © Microrusty.com 2021

Latest Release : 04/12/2021
Software written By Jim Merkle and Rusty Cain
Hardware design by Rusty Cain 

   Notes:                                                           
 The program only writes to the SD Card when there is a change in the AC Power Status from Power Good to Power Failure back to Power Good.      
 To set the DS3231 RTC You must use another program called : DS3231-Set-Time-Date.ino See link below for How to set.
 Serial Console Settings:  9600 Baud 8 bit.

Program creates a file with the filename "REBOOTS.TXT" that captures each time the system is power cycled. 

Example of REBOOTS.TXT file: 
 System Rebooted Date : 04/10/2021    Time : 14:31:37
 System Rebooted Date : 04/10/2021    Time : 17:02:21
 System Rebooted Date : 04/10/2021    Time : 20:24:53

The program checks the RTC Board and SD Card reader to ensure both devices are working.
Program sends SD Card reader status to console port.
Program sends power status to console port. 

Example : 
 Initializing SD card...Setting up logging time
 Power Good
 Data written to file:
 Power Good 

Program also creates a file called DATALOG.TXT that captures the Power status with date & time. 
Example of DATALOG.TXT file: 
 Power Good : Date : 04/10/2021    Time : 17:02:21
 Power Bad  : Date : 04/10/2021    Time : 17:08:36
 Power Good : Date : 04/10/2021    Time : 20:24:53
