The amount of time while the
state of the digital input should
not change to be recognized as a
new state. Too low debounce time
could produce multiple events on
the input change.
The debounce time is applied the same for all digital inputs. If you change
the debounce time for a digital input, the same debounce time is
automatically assigned to the others.
