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.

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.
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
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
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.

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 ... ?
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.
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).
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
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:)
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..
Hello GreatScott! I need i circuit which converts 12v DC to 5v DC. I used 78m05 ic but it just burnt. I also used a heat sink but still the ic burnt. Can you please a make a video on how to to this. The 12v DC source is a 110Ah battery.
Arif Khan How much current does your circuit draw? Do you have a heat sink? A 7805 is a linear regulator and burns off excess power as heat, so you need cooling if you're drawing more than a moderate amount of power. You'd probably be better served with a cheap switching power supply module rather than a linear regulation like a 7805.
Arif Khan The 7805s I have are only rated for one amp, so two amps will overload them. If you're drawing 2 amps with a 7 volt difference, you're asking the regulator to dissipate 14 watts of power. Even with a large heat sink, and assuming it's rated for that current (which it's not), it will get extremely hot and you'd likely need a fan or other active cooling. I'm not sure what the project you're building is, but a switching regulator is almost certainly the right choice for it.
Arif Khan Also, the 78m05 is only rated for 0.5 amps. No surprise it's burning when you're dramatically overloading it by a factor of four. As a starting point, take a look at the LM2576T-5. It's a switching regulator rated for 3 amps (giving you some overhead for safety), requires only a few external components (see the data sheet), and will produce a stable 5V. It costs about $2 USD, and you likely can buy pre-made modules for only slightly more. Plus, you don't lose the 14W of power you'd lose with a linear regulator, so your battery would last much longer. As always, read the datasheets. What is the nature of the project you're making?
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!
I’m an engineering student and these videos are more helpful then my actual lectures
same here

You are one of the few channels that actually uses the paid promotion feature. Thanks for doing this.
3:02 - That diagram told me everything. THANK you!
Lovely refresher course from my schools days too long ago to remember when. I gotta check out that PCB place.
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.

This is not at all what I thought a schimitt trigger was. Thank you for the information. I need some of these now.

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.
Ya ....he's back with pure electronics.....
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
How convenient, I just salvaged a Schmitt trigger IC.
Thanks for making a video on schmitt trigger, two days after i gave up on my project involving these xP
This was a very good explanation of a shmitt trigger. Thank you.
I didn't understand anything in this video... Loved it!
I wish my professors at university was at least half that good as you at teaching electronics.
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)
I know it's completely off-topic, but I realy like Your handwriting :D
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 :-)

i love your videos you are best electronic channel :)
cool video! I use hex inverting schmitt triggers for my synthesizers / electrical instruments
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 , ;)
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.

Another awesome video 👍
Can schmitt triggers be used to make active cables, like a 50 foot USB cable?
For debouncing and protection and some other details simply use the MAX6816.
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).
Dig or buy li ion BMS with monitoring and balancing. ??? great video. what does Schmitt think about this?
Can use this technique for Low voltage disconnect and reconnect in Battery charging???
Yes.
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?
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

Great job.
what about shift register ?
On my to do list
Perfect as always :)
Vout should be -5 v right why are you referring high and low it should be positive and negative right?
and most synthes uses them as the thing that creates the tone which gets fed into a binary counter to sequence.
Do a video about brushless motors and how to control them

Could that be able to work in ESC's???
Can you make a video about measuring voltage with arduino
@greatscott!_can u make a video on different uses of 18650 battery, i have alot of them lying idle
he did alot he made power bank for led strip and for mobile charging
ahmed elwan these are the only two uses that are available on internet, i am looking for something else
look for life hacks on youtube, which always have a design of an improper circuit and will kill the battery real quick
