Hi everyone,
I'm looking for a way to detect a knock pattern. something like:
toc----toc---------------toc
Getting the 'toc' shouldn't be a big problem: I'm planning on using a microphone or a piezo, and detect 'spike' of signal, corresponding to the knock themselves.
I mostly use Arduino, but open to any other solution. Anyone has an idea on how to 'record' the pattern, and recognize it with a certain 'room' for similar pattern, as 2 knock sequences will never be perfectly the same.
