[REPLicated2]

When I started dabbling in electronics recently, I ran into switch bouncing apparently as I used a push button to generate the "clock" input of a CD4017 decade counter and it showed rather erratic output behavior.

Adding a capacitor fixed it. Which reminds me that I should really invest in an oscilloscope to validate my (not so) educated guesses.

Great resource to read up on this topic, thanks.
