hello
there is an audio sensor to recognize
a tap of a finger on an object
thanks
Not sure of your application, but it seems like an accelerometer might be another (possibly more reliable) alternative for you if it could be mounted to the object.
I’d imagine you could implement something using audio pickup, as well as some sort of filtering to detect/isolate clicks … it just seems that this approach would be susceptible to random noise in the environment. Also, I’d think a finger tap would generate a highly variable output, from a fingernail click to almost no sound at all if just the tip of the finger was used.
Just some initial thoughts.

It’s probably what you are looking for.
You can even detect how hard the tap is.
