Hy
Ok no problem we can speak English!
You understand my situation?
I want when I play a note, my led shine the colour associate
For example one note it's a A . When I play this note, the yellow shine
It is possible with arduino?
Thanks for you answer. :wink:

It should be much easier when the Arduino knows which note it plays, much harder if it must determine the note from sound!

What to do when a chord is played?
