[Week 4_Class] Making Noise (Sound)

CODE

int speakerPin = 7;

void setup() {
// put your setup code here, to run once:
pinMode(speakerPin, OUTPUT);
}

void loop() {
for (int i=0;i<1000;i++){
// put your main code here, to run repeatedly:

digitalWrite(speakerPin, HIGH);
delayMicroseconds(500);
digitalWrite(speakerPin, LOW);
delayMicroseconds(500);
}

delay(1000);
}

By using code for making tone, we can make a melody. (Library)

https://www.arduino.cc/en/Tutorial/toneMelody

CODE

#include “pitches.h”

// notes in the melody:
int melody[] = {
NOTE_C4, NOTE_G3, NOTE_G3, NOTE_A3, NOTE_G3, 0, NOTE_B3, NOTE_C4
};

// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
4, 8, 8, 4, 4, 4, 4, 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() {
// no need to repeat the melody.
}
