Hi,
Im working on a project where i will activate a sound via a touch sensor. As one of the first steps I want to get the functions right. I have gotten the sensor to work but not the mp3 player.
I’m using a MP3 Player Shield v15 and an Arduino Uno.
I tried the test program “file player” and that one worked just fine.
Now a want to activate a sound through a button and i just can’t get any life in my system. I get a note in the serial monitor, nr 1 but no sound is coming out of the speakers… I have tried to get a solutions form google and tutorials but I just cant get what I’m doing wrong.
I would really appreciate any help 
Cheers,
