Tutorial 10 for Arduino: Interrupts and Hardware Debouncing

Why people recommend it

Part of an Arduino tutorial series covering hardware interrupts, often pointed to for its hardware debouncing of a push button with an RC filter and Schmitt trigger.

Watch for: Debounce section runs from around 2:45 to 8:45

In their words

Just revisited a video I had previously watched on hardware debouncing and in it they use the same exact setup (even the values) to debounce a momentary push button.
