Is there any way to make arduino recognize a series of timed presses of a button to make it similar to the knock lock project but instead using a button?
Any hint of how to do that??
The same way it was done with the lock. The only change is to read the button instead of reading a piezo.
So instead of analogRead(piezo)
And setting threshold to 1?
Was it really that simple? I've been searching for a lot of time...
Doesn't that make sense?
