I'm approacching to firefly and arduino. I did a lot of examples using LEDs and now I would like to use also the "AUDIO commands". I plugged the speaker in the board and then I used the Note to frequency command to get the frequency form the note, but when I try to connect the output of this command to the Digital pin 8, i can't hear any sound. Where's the problem? Thanks for your help. [Cattura](//res.cloudinary.com/moot/image/upload/t_d3-gallery-s3/v1414500056/:firefly:I8Ry:cattura.png.jpg)
