PianoDuino (Arduino + Processing + SoundCipher)

PianoDuino é um experimento simples que integra Arduino, Processing e uma biblioteca para manipular sons, a SoundCipher. A idéia serviu para experimentar o Multiplexador / Demultiplexador 4051.

    Será que tem como disponibilizar o esquema de ligações?
    valeu pelo projecto,,, esta muito bom mesmo.

    Pô vai dar um trampinho fazer este esquema, mas faz assim, se você entender como funciona o Mux/Demux 4051 (http://www.arduino.cc/playground/Learning/4051) você mata a solução do esquema.

    Boa sote, é facinho ;)

    Hi Bruno Soares, thanks for sharing this, I hope you understand my English, I used google translate to read you blog. I’m a student trying to implement part of this to my project.

    I’ve been trying out your example, after I survive the wiring, installation of program, I had problem testing the switches. I’m using usb serial port (com3), then run the arduino program and uploaded the program, and when i run processing, only a note is played. I press the button on arduino itself, the note play again but when I press the switches (on breadboard) no sound. I was hoping you could give a hint or guide as to what the problem might be :)

    Thanks Bruno Soares, Thanks so much for sharing your code!!! Haha Finally I got it working! Its the switch, they cannot be on the same slot on the breadboard. But from your photos, they seems to be on the same, nonetheless, thanks Bruno Soares!! hahaa
