/*
Clock project using two MX7219 matrix displays and the AdaFruit FX Soundboard
Provides date, time, temp, humidity and event notifications in rotating order
Also can chime in multiple ways, including Westminster chimes
Chimes are provided by Adafruit FX Soundboard in GPIO mode
There are some conditional options:
Davids_Clock changes some of the events and notifications
Extra_Display uses a small Adafruit 1306 OLED to continuously show date and time while the main display
rolls through its iterations
DDT includes a couple of small debugging (get it?) routines and opens serial terminal
*/

// Pushbutton 1 is the toggler , cycle between year, month, day, hours, minutes, seconds
// Pushbutton 2 is the increment up one
// Pushbutton 3 is the decrement down one
