Arduino (IoT): Simple Tutorial de Parlantes y Melodias Arduino

 

En tutorial aprendemos que los sonidos no son mas que energía y esa energía la podemos reproducir usando energía eléctrica en una Arduino.  El tutorial es sencillo y muy interesante porque, que mejor melodía que…bueno preparen el tutorial y escuchemos!  Será una muy buena sorpresa.

 

Conexiones

La conexión del cable rojo es al pin 8, que usamos como salida de la Arduino.

Codigo

El codigo sera en dos partes.  La primera parte es notas.h que básicamente solo define las notas.  La segunda parte es el código que usa esas notas.  Aquí esta notas.h:

La segunda parte seria melodia.ino:

#include "notas.h"
void setup() {     
pinMode(8, OUTPUT);   
pinMode(9, OUTPUT);       
digitalWrite(9,LOW);

}

// the loop routine runs over and over again forever:
void loop() {
  //tone(pin, note, duration)
    tone(8,LA3,Q); 
    delay(1+Q); //delay duration should always be 1 ms more than the note in order to separate them.
    tone(8,LA3,Q);
