Debounce a Switch

Physical buttons and switches can produce multiple outputs from a single
button press due to bouncing of the internal contacts. This video presents a
simple solution to eliminate multiple triggers from this effect.

Putting a Schmitt trigger for debouncing a switch is like killing a mosquito with an Inter Continental Ballistic Missile :)

This should be already implemented inside the microcontroller pins, if enabled...just like enabling internal pullup and pulldown resistors

Syntax error? Shouldn’t 00:21 start at 5V since the switch isn’t pushed and thus effectively be open so Vin = Vout = 5V?

You lost reaction Time from the Button.

if i recall right there is also a solution to the problem with a flipflop and some resistors

sir how should i connect the oscilloscope at 1:16 in multisim can you help....

Not very realistic unless it's the main switch in a factory.
