This script will check for events every 3 seconds
Even though the gap is longer than in ButtonPolling.py, becuase we
are using events we should not see any inputs missed
This is good that we dont miss inputs but capturing an event only occurs
once, so multiple button presses within 3 seconds are not picked up
