I’m an engineering student and these videos are more helpful then my actual lectures
same here
@@setrikaz9636 That's great and I'm so thankful for GreatScott's videos. The question is why are his 6 minute videos more helpful to us then the paid lectures we've sat through in college?🤔
@@Paradox3627505 school, college, university and all other of these things teach you many things, but usually those things you learned are outdated as hell and wont help you in real life situations.
I mean like the most mOdErN thing that schools may teach you is Arduino, which is a technology from 10 years ago, they dont teach you something to use in a year or so, they teach you what they already used in many years back
You won't imagine how that this video came perfectly on time for me, thank you
Thanks a lot! Also the "freshen up an old signal" hint is valuable. Just wanted to leave a thank you here, since you helped me also a lot and I watched a lot of your videos.
Thanks for the support :-)
You are one of the few channels that actually uses the paid promotion feature. Thanks for doing this.
Lovely refresher course from my schools days too long ago to remember when. I gotta check out that PCB place.
Thanks a lot. Your videos help a lot for homework assignments, lab reports and lab work. You're beyond awesome.
3:02 - That diagram told me everything. THANK you!
You can also use a 555 timer IC as a schimitt trigger
what can't you use it for?
XD
555 also contains opamp
Luiz Fernando you can also use a 555 for combing your hair and cleaning the dirt from under your fingernails... without even a battery! They are very versatile, if a bit old-school.
Ray, I made an extremely loud noise with one the other day without a battery. I had dropped one on the floor. It landed legs up. I was barefoot and found the chip. The noise generated scared the cat out of the shop.
This is not at all what I thought a schimitt trigger was. Thank you for the information. I need some of these now.
The high/low values for the inputs in the datasheet of a microcontroller (or pretty much any digital input pin of any logic circuit) are not equivalent to those of a schmitt trigger. They tell you what will definitely be seen as high or low voltage, but the outcome for everything in between is undefined.
superdau good point. The mistake slipped past me, thanks for the reminder.
I was just desingning a project on software - hardware and had to take in count those problems, I already knew all you said there and it was very crazy that you uploaded it the same time I was working with that haahha, had to make the subtitles on spanish!
Enjoy the subtitles!, thanks for all your work
Glad you liked it :-)
Ya ....he's back with pure electronics.....
This was a very good explanation of a shmitt trigger. Thank you.
I wish my professors at university was at least half that good as you at teaching electronics.
How convenient, I just salvaged a Schmitt trigger IC.
Wooaa, kinda over my pay grade!
... Didn't quite match my query towards a simple explanation for the incorporation of the Schmitt Trigger into a touch probe sensor circuit.
Very well done though. Thank You
Hey I have a question, maybe in the next video you would like to talk about how to connect and handle the gyroscope for ardruino , ;)
thank you very much mr scott your videos are amazing
Thanks for making a video on schmitt trigger, two days after i gave up on my project involving these xP
Doofenschmitt Trigerrinator?
When i was a kid, something something baloons parents something
using an op-amp as a comparator can have quit few pitfalls. Some op-amps have protection diodes between the +/- inputs so you can have more than a few 100mV between them and some op-amps invert their output when they hit the rail
WOW! Schmitt triggers are awesome! thanks for the video.
I didn't understand anything in this video... Loved it!
Hey, greatt video, could you make make an H-bridge with N Chanel MOSFET logic or standard for controlling DC motors at High currents and you could do a DIY VS BUY if you want, In the internet Theresa is a little information about this.
Thanks for making a video at this topic! I red an article on it 2 days ago but had no clue how it works. Keep the niveaful content up 👍
Thanks for the feedback :-)
cool video! I use hex inverting schmitt triggers for my synthesizers / electrical instruments
Plz do a vid about MOV's metal oxide varistors, I can't find much solid info on them, you seem like a pretty reputable source so your video will probably get first at the top of the search results.
You should make a synth. Maybe a simple one from music from out space
I watch your videos just to hear "Let's get started"
Can you do video about I2C protocol?
This little thingy helped me get rid of 100 lines of code from my Arduino project :D
Sweet!
Yes, if you are using code to debounce your switches.
I'll be using it to debounce some variable resistors (those flexible resistors)
*Why do you keep saying shipping on JLCPCB is free? Am I doing something wrong? I'm always getting at least 10 dollars shipping with Registered Air Mail.*
Same here
"keep saying"? I did not mention the free shipping in the last videos. If you experience problems with the coupon then contact JLCPCB. That always worked so far.
GreatScott! You did mention it in the video "currently with free shipping" ;)
Island Monkey for your first order only. Probably not for registered air mail though.
Btw, what I hate about PCB manufacturers that price is hard to compare :( They seem to compete with the price of the board, but shipping is always more then the price of small boards. And "surely" there is no easy way to know what will be the total cost anyway for you in advance, so it's hard to compare all of these manufacturers based on the total cost, what people would be interested more (I guess) rather than some "imaginary" price which is never what you have to pay (ie, the "without shipping cost" price). Ok, for JLCPCB , probably shipping is free for the first order, that's true, but I meant in general. I would prefer a fixed price with ALL things included from all manufacturers (for about the same PCB surely) so it's much nicer to check and compare prices then. But I guess this is exactly what they don't want us to be able to do ... ?
Awesome tutorial
Thank you Sir you make the best tutorials!!!!!!!!!!!!!
I know it's completely off-topic, but I realy like Your handwriting :D
Hey Scott,can you make video about DIY electrical guitar and how it work.
For debouncing and protection and some other details simply use the MAX6816.
Do a video about brushless motors and how to control them
Can you make a video about general purpose parts you should always have on hand
What is the name of CRO used in this video? This CRO was very precise and advanced
Please Publish some Op Amp related tutorials. Thanks for the nice video
i did enjoy the video, very good explained thanks!
Can you make a video about shift registers?
video on bootstrapping needed
Very interesting. Thank you.
BTW, I like that ad. It reminds me I want to get into pcb design again and try to get my first pcb design printed.
Thanks
Please make video to explain how to use arduino as usb serial converter
Thanks great scoot
i love your videos you are best electronic channel :)
Would you make a video about bootstrapping in mosfets?
It is on my to do list
on a circuit bord we make on school 3 schimitt trigger's are used to boost a 9 volt battery to 30 volts only using diodes an elecrtrolitic capasitors no external power is used only the 9 volt batery ter is no induktors and transformers on the circuit bord
Hi Great Scott
I like your work
Can you use the schmidt trigger for a subwoofer circuit to only let pass the high voltage peaks comming from the bass?
Because i am trying to build one on my own and not copy circuits from the internet.
And keep up the work. Your videos really help:)
Great job.
Make videos on iot projects because they are famous in this tins
great video and keep up the good work, i was wandering if you were planing to make a video on the hall effect sensor ;)
what about shift register ?
On my to do list
very good
Great video
GreatScott, can you try to use a Schmitt trigger to make a power button? So you would have one button to turn on/off an Arduino or any other device(from 0-3Amperes).
and most synthes uses them as the thing that creates the tone which gets fed into a binary counter to sequence.
Yeah, blissful education.
Please make a video on MOSFET gate drives. IR2110 IC
Great video; as always! Keep on with such great videos!
As a suggestion a LoRa video with be great to see in the near future :)
Dig or buy li ion BMS with monitoring and balancing. ??? great video. what does Schmitt think about this?
Is there any kind of electronic project which Scott does not do?
when you will make a video on bootstrapping I am waiting for very long...
It is on my to do list
Can use this technique for Low voltage disconnect and reconnect in Battery charging???
Yes.
You should do more Raspberry Pi (or other single-board computer) projects.
Hey! @GreadScott! nice video, please you can talk about the analog multipliers? c: saludos!
Can you do a video on electronics diagnostics, like finding a short or a dead component in a circuit board, please ;)
As a male 27 year old, computer nerd and DIY fan I can say 1 thing about your videos: Im 97% lost when watching them xD
Still love them though :D
Sir you haven't build a good boom box for a long time. So please make a speaker box using a PAM 8610 class d amplifier
Another awesome video 👍
I want to make the same thing for low battery cut off and I want hysteresis to be adjustable upto 1V .
How can I achieve that sir?
74LS132P confusing me !! 😵😵😭😭 , it's datasheet is also very confusing , i wanna test this ic , but I don't know whether its Nand gate connected before of schmitt trigger or after that ???? By powering ic with 5v I measured its output voltage on its one ( two input Nand-schmitt ) that is 0.9 v on input A and B and 0.3v on its output Y !!!!! , it is ok to test one input schmit trigger for me !!! but ------ " How to test ' two Input schmitt with Nand ' Output With Hysteresis ????? Datasheet shows :// - on Vcc= 5V , VTh+ = 1.5 To 2V max ,, VTh- = 0.6 to 1.1V max !!!!?? and vth+ to vth- = 0.4 to 0.8 type ????? any one tell how to test it using potentiometers and multimeters ?????
Amazing coincidence! I just ordered a tube of 74HC14’s a week ago for a project to “de-bounce” a set of push buttons on a control panel! Thank you for the great video as always. Trying to learn how to make a custom shape PCB... can anyone help?
James Childs custom shape as in the outline of the fibreglass board itself? The cheapest way is probably a hand held fretsaw. Practice on some scrap cos they're not the easiest things to control neatly..
Vout should be -5 v right why are you referring high and low it should be positive and negative right?
Plese make a video on cnc machine and coding..
Can you make a video about measuring voltage with arduino
Can you make a video on how to make a variable speed fan controller for a computer
thank you for the German reference. Vielen Dank..
Can schmitt triggers be used to make active cables, like a 50 foot USB cable?
Really, really nice! 😊
currently with free shipping?
Do Schmitt triggers introduce a small amount of hysteresis into the equation versus the way op amps behave? I'm guessing that's what's happening.
EDIT: Ahh, you just mentioned it in the video as I was watching. Thanks for the video!
About a volt
DIY smart glass??
Love your videos!
Hey, nice video, are you building your own vesc for the quadcopter or for the longboard? I think it seen your previous videos, am i right?
so breadboards but only for basics videos?
i got metcal sodering tips .i know that it will work in 13Mhz Hf .can you possible to make a cheep metacal soldering station
Where do you get your electronic components from...pls tell??
Please tell me the software you used for schematic design.
Can the Schimitt trigger be used to clean noisy gyro on Flight controllers?
Wrong intro it is electronic basic change it.
Great video keep it up one of the best educational channel on UA-cam. Very close to 1 mill
Please do it.
Nice wave generator.
Could you make your own Arduino using JLCPCB? if you were to source your own components would it work the same?
Perfect as always :)
Is it possible to change the trigger voltage or hysteresis on the sn74hc14?

very good, many many thanks ;-)
