Does a switch really bounce? Debouncing?

Since the inception of micro-controllors (Digital) the bouncing of switches has become a issue to consider in the hardware or software design.

I use an oscilloscope to show the bouncing affect on two common switches, as well as use analog persistence to SHOW the effects more visually.

    Very interesting and unique use of Persistance Mode on the Osciloscope to display evidence of De-Bouncing. Well done.

    Cool. This is a great way to use the scope.
