Hi guys,
Im working on a project where i want to detect vibrations on a surface with a piezoelectric element attached on that surface.
Further down the road I want to be able to detect the distance between the source of the vibration and the piezo element based on the strength of the vibration.
I followed the knock example from the arduino library but the only thing I managed to achieve is to register a response only if I'm pressing the piezo but it returns 0 if I knock next to the piezo. Can t be that the piezo I'm using is not sensitive enough, or any ideas what I might be doing wrong?
Thanks alot
