Dust trigger pin changed to 4 on new ODIN PCB
Interrupt pinmode set to INPUT_PULLUP
Swapped SDA/SCL pins, moved RTC alarm trigger to Arduino pin 2 interrupt. RGB led leg on pin 2 moved to pin 8. Libraries added as some parts within libraries modified.
ODIN sleeps until interrupt on pin 2 is triggered. RTC alarm provides interrupt. RTC no longer connected to pin 8.
Added arduino sleep. Alarm from RTC used as interrupt on pin 2 to wake arduino. RTC alarm no longer connected to pin 8.
