37) Contact Bounce & Debounce Basics

Today we’re looking at contact bounce. Together with an oscilloscope and high speed camera, we can see a little more closely what happens during contact bounce. We also look at ways to mitigate this issue and show the effects of hardware debounce.

Another good resource for information on debounce is available at Jack Ganssle’s website:

A HUGE thanks to David Kronstein for lending me a Cronos 1.4 high speed camera which I used to make close up and detailed video of said bounce. http://www.krontech.ca/
