En esta ocasión, les comparto un proyecto muy interesante, que nos permitirá conocer algunos conceptos como por ejemplo, cómo funciona un botón pulsador, qué son las configuración es Pull Up y Pull Down, y cómo podemos reproducir cualquier canción en nuestro Arduino.

Componentes

  • 1 Arduino UNO
  • 1 Buzzer
  • 19 Jumpers Macho – Macho
  • 9 Push Buttons
  • 1 Protoboard 400p

En realidad, cada uno de los pines que se muestran, van conectados hacia un Push Button. Si tienes dudas, te enseño a continuación:

  1. Se coloca el Pulsador sobre el protoboard, de esta forma:

2) Se conecta un jumper, desde la salida del pulsador hacia uno de los pines del Arduino:

piano midi con arduino
piano midi con arduino

3) La otra patilla del pulsador, la conectaremos al carril GND, en mi caso, he utilizado un pequeño cable obtenido de un cable RJ45, para hacer más fácil la instalación, aunque si compras el producto que te he recomendado, ya tendrás jumpers de este tamaño y que se ajustan de una mejor forma:

Esta misma acción, la repetiremos para cada uno de los pulsadores, de tal forma, que debería quedarte algo así la conexión:

No podemos olvidarnos de la bocina, ésta la conectaremos al pin número 11. El cable color rojo va al pin, y el de color negro va a GND.

Esto es todo lo que se necesita para este proyecto en cuanto a conexiones se refiere.
