Bolas de Dragón con arduino
Bolas de dragón (serie de Dragón Ball)
Juego de luces y sonido.
Material usado:
x1 Arduino Nanox1 Placa de Mp3 C4B6
x1 Tarjeta SD
x7 Led Neopixel WS2812B
x3 Pulsadores
Arduino Nano pines y Mp3
Primera parte, hacer los juegos de luces con arduino y los neopixeles.
Segunda parte programar la música a través de una tarjeta SD y la placa Mp3.
*Según la placa Mp3. las salidas A1-A10 se activan con GND, es decir con pulsos negativos.
Para guardar las canciones en la tarjeta SD (8GB en adelante), se creará una carpeta 001.
Las canciones se nombrarán como 001,002,003...999.
A través de una caja de pulsadores que hice con la configuración de Pull Up, puedo cambiar las canciones a voluntad.
Os dejo aquí abajo los pines de entrada y salidas del arduino.
