Debounce a Switch

[@maser9433]

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

[@joakinsa]

Not really the same magnitude but the comparison is still funny

[@MaltWhiskey]

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

[@lukealadeen7836]

They have it the wrong way around but we all get what they meant

[@justinc2633]

that picture showed what it should read based off the state of the button, noithing wrong with it

[@smartgooglelocalguide3560]

The waveform was just captured for demonstration purposes; it was meant to show the behavior not to show the rising or falling voltages, etc.

[@serdarxxx1073]

You lost reaction Time from the Button.

How to calculate r1 and c1 values???

[@RoboLife41]

Look here: www.electronics-tutorials.ws/rc/rc_1.html (RC Time Constant, Tau)

220

[@alejandroperez5368]

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

[@byugrad1024]

The size of the cap needed to do this would be astronomical to put it on the die.

[@msimon6808]

For zero debounce delay something like this with counters for delay instead of RC. spacetimepro.blogspot.com/2023/09/switch-debouncer.html

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

[@sohailquadri9253]

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

[@rokiedecentra9656]

just Vout and Ground.................

[@Cyklonus]

👍👍

[@urugulu1656]

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

[@First2ner]

yes, there should be. Two resistors and RS FF other options here: electrosome.com/switch-debouncing/
