Hi everybody !
I want to use 3 (or more) knock sensors. So I had read knock tuto from arduino website and I had created this montage (attachment image).
But when all analogs in receive once knock. For example, if i knock on the top knock sensor, A3, A4 and A5 receive in same time the knock signal.
What am I doing to fix it ?
Thanks you very much and sorry about my approximate english language.
