Tiva C launchpad Playing Music

Hola!


En este tutorial conectaremos a la Tiva C series TM4C123G  un piezo eléctrico (Buzzer) para hacer sonar divertidas melodías.

Materiales:

-Buzzer
-Tiva C launchpad
-Resistencia de  220 ohm o aproximado

Se interconectara el piezo de la siguiente manera a la tiva:

La positiva a la resistencia y esta al pin PF2 que viene siendo el pin digital 40 y el otro lado se conecta a tierra, si al conectar no sabes cual es la tierra simple no sonara al cambiar la posición sonara.

Figura 1. Esquema de conexión

En este caso escucharemos las melodías:

HBD- Cumpleaños feliz
Konami contra- soundtrack videogame
Imperial March- Star Wars
Let It Be- The Beatles

De los códigos 3 puedes encontrarlos en los ejemplos que trae el software Energía los cuales podrán modificar a su gusto

Figura 2. Energía Examples

Y Let it be puedes hacer una adaptacion del tradicional hecho para Arduino http://forum.arduino.cc/index.php?topic=3309.0

A continuación les dejo los que use y al final el vídeo de como funciona!
