Hola,
hace poco trate de seguir una guía en youtube para utilizar un Arduino nano y un adafruit audio fx adjunto el link.
Ghostbusters Proton Pack Sound Effects: Build Your Own / How-To, DIY Electronics w/Arduino 
(youtube.com)
El problema que tengo es que despues de mucho tiempo revisando las conexiones y tratando de ver el codigo en arduino ide (del cual no se nada)
me persiste un problema que al dejar de apretar el boton de disparo el sonido se sigue reproduciendo hasta overheat siendo que al soltarlo deberia sonar el de fire stop.
Adjunto el serial que me da Arduino IDE desde que enciendo power switch on, primer disparo shields on y despues fire start.
