ClickVersusDoubleClickUsingBoth.ino (2244B)
      1 /*
      2  * A demo that combines the techniques of ClickVersusDoubleClickUsingReleased
      3  * and ClickVersusDoubleClickUsingSuppression by using both event types to
      4  * trigger a "Clicked". I think this is the best of both worlds. If someone does
      5  * a simple Press/Release, the Release gets triggered. If someone does a quick
      6  * click, then a Click gets triggers (after a delay to wait for the potential
      7  * DoubleClick).
      8  *
