Jukebox + Arduino

Introduction: Jukebox + Arduino

Este proyecto consistió en crear una Rocola Digital a través de una programación de Arduino. Su función es muy simple y no es muy difícil de crear. La Rocola tiene muchas funciones interesantes, y una de ellas es que a través de una pantalla LCD se muestra el nombre de la canción que se esta reproduciendo, y que para cada canción se muestra un color distinto a través de un led RGB. Así mismo, a través de dos pulsadores puedes cambiar de canción (de izquierda a derecha o viceversa). Aquí te mostraré paso a paso en como crear uno de una forma sencilla y creativa.

Step 1: ¿Como Funciona?

Step 2: Circuito Armado Y Sus Materiales

¡Es necesario que tengas estos materiales para hacer que tu Rocola funcione!

- Arduino UNO

- Pantalla LCD 16x2 + Interfaz I2C

- Protoboard + Mini Protoboard

- Led RGB

- Passive Buzzer

- Jumpers Para Protoboard

- 2 Pulsadores Eléctricos

- Caja para el Circuito

Step 3: Diagrama Esquemático Del Circuito Electrónico

Step 4: Técnicas Para La Construcción De La Lámpara

Como te comentaba, el crear una Rocola no es tan difícil como aparenta. Aquí te dare unas técnicas que te serán útiles para poder hacer que tu Rocola funcione.

- Es necesario que consigas cada material que se muestra en "Step 2"

- Es necesario que tengas un "Arduino UNO", al igual que la aplicación para poder hacer que la programación funcione.

- Crea el circuito físico el cual te muestro en "Step 2".

- Luego de tener todo armado copia la programación el cual te mostraré en el ultimo paso.

- Por último, usa tu creatividad y consigue algo que tengas en tu casa para poder hacer la mejor Rocola de tu vida y no te olvides en decorarla a tu criterio.

Step 5: Código De La Rocola

//Creado por: Jorge Aragón 

//Incluir librerias para la pantalla LCD con interfaz I2C
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);

const int buzzer = 11;
int contador = 0;
int R = 6;
int G = 9;
int B = 10;

int subir;
int bajar;
