PianoDuino (Arduino + Processing + SoundCipher)

Posted in Arduino, C++, Electronics, Processing on maio 30th, 2009 by Bruno Soares – 21 Comments

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