/*

Quick sketch as PoC for viability of using Cree Connected LED's zigbee board to drive other devices (a speaker in this case).
Modified by Buddy Crotty - March 2015
version 0.1.2

Completely copied from Tom Igoe's example sketches: 

  State change detection (edge detection)

// this constant won't change:

int buttonPushCounter = 0;   // counter for the number of button presses
int buttonState = 0;         // current state of the button
int lastButtonState = 0;     // previous state of the button

int melody[] = {
  NOTE_GS2, NOTE_GS2, NOTE_B2, NOTE_GS2, NOTE_FS2, NOTE_E2, NOTE_DS2

      // iterate over the notes of the melody:
    for (int thisNote = 0; thisNote < 8; thisNote++) {

    // to calculate the note duration, take one second
    // divided by the note type.
    //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.

    tone(speakerPin, melody[thisNote], noteDuration);

    // to distinguish the notes, set a minimum time between them.
    // the note's duration + 30% seems to work well:

  //for next time through the loop

  // turns on the Chime every two state changes (only when the door opens)
  // the modulo function gives you the remainder of
  // the division of two numbers:
