2 Tutorial 10 for Arduino: Interrupts and Hardware Debouncing
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.
3 Monostable 555 timer - 8-bit computer clock - part 2
An episode from an 8-bit computer build series, explaining how a 555 timer provides the clock and handles debouncing, praised for laying out the theory clearly.
4 EEVblog #961 - Monkey Debouncing
Dave Jones explains switch and relay contact bounce and the hardware and software ways to debounce it; recommended when microcontroller interrupts misfire on noisy inputs.
5 Digital Electronics: Debouncing a Push Button Switch (SPST)
Explains hardware debouncing of switches with an RC network feeding a Schmitt trigger inverter, part of a series people cite when cleaning up clock inputs.
