I'm much more of a software guy and handle denouncing of buttons and rotary encoders in my projects problematically, so it was very cool to see that Schmitt trigger in action, thanks!
Thanks for this very clear explanation. Well done!
You actually explained it in a way I can understand!
thats a great, simplified, and clear explanation! keep up the good work ..
and for arduino users, note that you can make a software debouncer ...
Very good explanation, thanks you for what you do!
Original :) .. every time we used software debouncer! But we needed to go hardcore with this!! THANKS ♡
Thank u for your clear explanation, that help me a lot
Thanks for a brilliant video
Thank you very much! It help me in my project.
very good explanation! easy and clear! thank you for sharing it with us
Lots of folks can clearly communicate bad information. Ever been to a bar? This channel is like that.
Thank you!
its so usefulr. What is the maximum frequency that can be measured with this circuit?
Heathkit! That's a name from my youth ...
Thank you so much for the explanation. I am just starting Arduino after an almost 30 year hiatus from electronics and programming. Good stuff!
Thank you so much :D You helped me in my project ñ.ñ
شكرا يا هندسه ✌️✌️
3.56 how capacitor will charge to 5v since resistor drops some voltage...
Thank you for detailed video! Are the values of resistors and capacitors the same if I'm using 3.3V as input instead of 5?
Yes you can use the same values or use software debouncing techniques.
Thank you!
@@tmc200527 Che valori hai usato?
thank
Is there a way to accomplish this without a Schmitt trigger? I don't have that chip and I need to get this interrupt working...
You can also use software debouncing method. th-cam.com/video/xvfHu7QIfP0/w-d-xo.html
06:15 If you put the second resistor there, then the output will never be equal to the Ground potential. Instead, it should have been placed just next to the capacitor in series.
a bit late here but still hope you can reply,
Next to it after the switch and capacitor or before? thanks
@@vladurs6475 just watch this one...way better... th-cam.com/video/9UKM0vlHGkI/w-d-xo.html
@@user-hc7mi7ft9x you linked the same video. maybe paste wrong url?
Sir, can you please provide me its schematic diagram.
@1:15 you are fundamentally wrong! an encoder (at least the most common and cheap ones picked up by diy projects with arduino o the RPi) is exactly a series of mechanical contacts being switched in any direction by free hand! the amount of noise you get between detents is pretty high (and in the cheapest chinese models is insane) so it's MANDATORY to implement a heavy debouncing method, being it by hardware (rc smothing) or software (validation algorythms) or both (most efficient)
if i have 16 buttons how many capacitors do i need?
I guess it would depend on the topology of your circuit. If you were monitoring one input to see if any one of 16 buttons in parallel was pressed you could use one cap. If you are monitoring 16 separate inputs you would need one cap for each.
It's parallel-in serial-out, so I guess it's the first case. Thank you.
1) You didn't prove that the switch is properly debounced !
2) Why are there no switch(es) debouncer(s)/switch(es)+debouncer(s) modules available ANYWHERE ???
How do you mess up your sound this badly? Cannot watch.
