I thought this was a great video for me as it cleared up several uncertainties I had. This video was straight to the point very clearly. Looks like it was posted 2 years ago... I can't believe there are only 74 comments. That said, I thank you for helping me realize I was over complicating what comparators do and how.
Brilliant, this is how you should show things. With schematics, graphs, and practically performing. Keep up the good work. I really learned the voltage comparator in only 17 minutes. Thank you very much.
EXCELLENT video and tutorial the whole way through. I really loved it! Thank you for refreshing my theory and application. I really needed it! PS. your voice is quite relaxing to listen to :P ! Makes the video easy to watch. PPS. Small conversational English tip for speaking about units : when you speak of temperature, you do not need to say (x) degrees OF celsius - you can just say (x) degrees celcius - the same way you would say (x) metres, not (x) OF metres. It is probably because you are a mathematician too (:
A better example would be if you used a zener to establish Vref - because your comparator desdign relies on a completely stable Vcc. If you are (for instance) monitoring a battery output voltage and using the battery for Vcc you need a zener to produce a reference below the minimum battery voltage and a potential divider for the Vcc to Gnd - giving an absolute general purpose comparator design that works over a range of source and target voltages (especially if you put a variable resistor into the potential divider).
Dear , Miliohm thank you for this grand explanation ! From your diagram COMP. it sparked my mind to ask the limitation to use comparator in place of OPtacoupler for feedback power regulator STR ? thanks again.
Congratulations. Now you could make a video with a CTN and only one transistor which controls a relay for controlled fan based on temperature. Thank you for sharing.
You all probably dont give a shit but does anybody know of a tool to get back into an Instagram account..? I stupidly lost the password. I love any assistance you can give me.
@Ben Raphael Thanks for your reply. I got to the site on google and I'm in the hacking process atm. Seems to take a while so I will reply here later with my results.
I am Little bit confuse . if in inverting vin less than reference volatge than out out will bhi high and in inverting and non inverting comparator you showing that is vin e low respect of reference voltage than out but will be zero
@@allabouttech5689 the output of the sensor will be so small. I think you will need an amplifier, and it's little complicated to build one. But you can google for it. Then you can use the output of the amplifier to the comparator input.
@@miliohm Thanks, but with the help of your tutorial I was able to build the heat sensor using thermocouple and also NPN transistor that is 2n3904 relay and everything works fine, but if I use PNP transistor 2n4906 it keep turning ON and off the relay. Please do have any idea that can help I will really appreciate it.
using 120/240V on a breadboard is not a wise thing to do. Putting the relay away of it and activating it with wires going outside the breadboard is much safer for both the equipment and the operator. Same : don't use flames. There are many safer and inexpensive ways to heat the sensor to 35°C than using a lighter. Finally… well, the application of such circuits is barely what I consider real life. Generally we don't need a temperature threshold to light something up (a photoresistor might be a better choice) nor we need a relay to turn a low voltage DC fan on (a small transistor is enough). Maybe a good application might be to use the temp sensor on the transistor to make a crude temp protection for it. All in all, the analog sensors are not precise and have high tolerances. In real life, digital ones are often less of a hassle and that's why we use small microcontrollers instead of simple comparators, or on the other side engineers use inexpensive electro-mechanical circuit-breaker thermostats on many industrial and home appliances, no electronics required.

I'm 2 years before getting to the party but this was a good one. Thank you.
Your way to explain it is brilliant! I watched several other videos but still couldn’t get it, you made it very simple and clear. Thank you.
Best explanation I’ve seen. You helped immensely. Would love to see more from you from this basic series . Subscribed and liked!

Thank you!
This was a really good video with good examples, math, and practical application. I hope to see more.
You are such a excellent teacher I think you should do more electronics videos for sure..
Thank you! Really appreciate it!

I watch so many video to understand op amp non of the video make sense! when i saw this video everything clear like a fog.thanks make more video.
Fantastic teaching and clear concise explanations!
Very good explanation and demo project. Thank you so much.
Your explanations are very well understood.Tnx
Thank you very much and iam very impressed with your explation from basics to application step by step.
Thank you so much!
Thanks, easy to understand with real example
But I don't understand that why you connect the 4.7k Load between VCC and output. At 9:03
That's called pull up resistor. Try google it
Excellent tutorial great 👍🏻 This is how to learn electronics thank you 🙏
Good experiment sir keep up the good work
Excellent. Exactly what I need. Thank you !!
Good explanation can understand properly very good
Make a video on OP-AMPS just like this.
Absolutely excellent !!!
Thank you! Really appreciate it!
This was so perfect
The experiment is extraordinary, I am amazed as an Indonesian. Reply my boss

Thanks!
Thank you very much teacher
Thanks a million, very good video , easy to understand.
Thank you!
your are amazing. this helped me a lot
Please post me a video of how this comparator works in audio circuit
Old school. And billions of these chips in through-hole form factor are still out there.
You are wow I need your coaching
I am Little bit confuse . if in inverting vin less than reference volatge than out out will bhi high
and in inverting and non inverting comparator you showing that is vin e low respect of reference voltage than out but will be zero
What is the voltage of Vout?
excellent!
Hi, what is the purpose of 4.7k ohm resistor 8:52
It's called pull up resistor. You can googling that term.
@@miliohm thanks a lot
Need a freewheeling diode across the relay's coil.
What voltage of relay are you using?
It's 5V
why is the fan keeps spinning after the fire is removed?
Sir instead of using lm35 can I use a thermocouple and how to use it as Vin or on non-inverting pin?
What kind of thermocouple?
@@miliohm Type k thermocouple
@@miliohm Hello sir it's K type thermocouple
