Thank you for your help!
The code below is what is currently uploaded on the board. Where "door" is a photo electric sensor over a door way and "evac" is a push button to activate the second tone. Haven't wrote the tone for evac yet.
*/
#include "pitches.h"
// notes in the melody:
int melody[] = {
NOTE_D3, NOTE_D5,NOTE_D6, };
int door = 1;
int evac = 2;
// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
10,4,10,4,10,4,10,4 };
void setup() {
// 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.
int noteDuration = 1000/noteDurations[thisNote];
tone(8, melody[thisNote],noteDuration);
// to distinguish the notes, set a minimum time between them.
// the note's duration + 30% seems to work well:
int pauseBetweenNotes = noteDuration * 1.30;
delay(pauseBetweenNotes);
// stop the tone playing:
noTone(8);
}
}
void loop() {if (door = HIGH);// no need to repeat the melody.
}
