Pulse Width Modulation (PWM) - Electronics Basics 23 

Thank you - well done - I am just starting to learn about circuits and at age 70, the better the explanation the easier to grasp.

It is truly inspirational to see that there are people like you who love what they do and also have the gift of transferring complex information in such a simplified way. If every teacher was like you, our education system would be flourishing. This really helped me today. thank you very much and God bless you.

Incredible way of explaining things. I know this video is 7 years old now, but the way you presented everything here is top tier

What a fantastic explanation! At first I didn't quite understand the entire concept. It wasn't until you introduced the much slower, 502 Hz frequency that it all clicked... Thanks, teacher!

You are doing great things for mankind with this series. I didn't really understand it until you showed the Arduino then it made sense.

I am a Civil Engineering student, studying Power Electronics as an Elective. Everything is explained so easily to clear the basics. Thanks You..!

Thank you so much for this video. I've been trying to wrap my head around the concept of a PWM solenoid that controls a hydraulic circuit. Now I get it.

Well explained. I did not see anyone explained it better than the way you did. Keep going mate!

one of the best explained pwm videos

thanks a lot. tutorial video was absolutely great. I'm gonna share this with all my classrooms.

Thanks for the real life example! This cleared up a lot of questions I had!

The best channel which I was never gone through.

you are awesome thank you much your videos are much better than most

Thank you very much. Excellent videos- They are short, detailed and simply explained.

Great video! I just recently found your channel, and i have really learnt a lot so far. Keep up the good work!

I wish you'd been my lecturer at tech when I was a student... It's soooooo much simpler the way you describe and demonstrate it

This video finally helped me understand what pulse width modulation was. Thanks!

Very useful video!

Simply great- simple n to the point explanation! keep it up!

Thanks a lot... it really cleared my confusions on pwm... thanks a lot again

Great accurate explaination

another excellent video. keep up the good work.

You have answered the question I had about the PWM power supply that I had at the beginning by adding the arduinho at the end. I note that the variable potentiometer has flat pins, do they fit into the breadboard without damaging it? I look forward to your introduction on the arduinho,

Very good explanation!!!

Very well explained, thanks!

I deal with PWM on cars at work and after watching this video was made it more easier to understand

very well explained.

Great explanation. You are a great teacher....

Very clear and simple explanation, thank you very much

This was a great video. Thank you.

Excellent explanation from the presenter.

Great explanation, thank you

After I get my prepaid card, I will buy EveryCircuit. I am now addicted to that app.

มีประโยชน์ วีดีโอสัญญลักษ์ ทำให้เข้าใจง่ายขึ้น คงต้องไปทำการทดลองต่อ

awesome explanation !!

I learn a lot guys thank's tech us more

Nice video.Thanks for sharing

Well done, thanks a lot for clear explanation

Great Video well done

beautifully explained

Great explanation, God Bless.

Thanks for so good explanation.

Very good description

thank you so much for making this video

Really good explanation and good clear unterstandable english for a german :)

very informative and understandable for people from off engineering field

great videos!!

great video!

nice. it was very helpfull

One of the best video i have seen, u have cleared all my doubts, Thank you sir and can you please suggest how to move further in this stream to the next level as i want to take electronics as my career, please suggest as it helps me alot

your teaching is very good .. plz teach us what is 555 timer

অনেক ধন্যবাদ বস! I was confused between the difference of a PWM device and a switch. Now it's clarified strikingly!

Good video. I'm just starting with Arduino. Did you have the variable resistor being input to a sketch, which then sent a calculated width to the led? What freqency does the Arduino send the pulses at? Can that frequency be controlled as well? Thanks, going to watch a lot more.

Very nice! 👍

Very nice, friend, greetings from brazil!

Thanks for your wisdom 👌👌👌

Great videos

bravo, well done

Thanks - well done

I like this explanation

Great presentation, please which simulator you are using?

Great video, very helpful. What software are you using in the video, it's quite impressive.

Great job thanks sir very useful thanks

To have a given amount of light dimming effect (ex: 30cd ), is the power consumption the same when : a) A resistor is used to drop the voltage b) PWM is used

Came here looking for PWM explanation in synthesizers, stayed for content.

Recently found your channel, which is great. Could you do a video on a switch mode power supply? Also what program are you using to demonstrate these circuits?

Greatt video Thank you!!

I accidentally stooped by if I can study synthesizer :-) But good information too!

fascinating

This is fantastic explain about this circuit. Can you upload forward and flyback dc to dc topologie videos.

Great video. I'm curious. Doesn't the potentiometer change the resistance of the circuit? Nothing really to do with the pulse width or hertz right ?

well explanation

you are explaining in gud way..keep going gud, and reply me that, which tool u using?

Excellent ✌️

Would you like something fit for the HHO generator and to make it look this circuit ??

excellent

Excellent video! Do you have one showing the next step; making a sine wave?

Thank you.

so basically can pulse width modulation be summed up in the following sentence: power switched on every x secs for a period of y secs where x is called the frequency and y is called the width, and is given as a percentage of the total frequency period?

Can you provide example of PWM with variable frequency drives (VFD) to control motors?

Mr Feynman is smiling from the quantum realm.

Thank you

Great explanation! How would the schematic look for this circuit with a potentiometer included?

Impressive presentation! Could u plz mention the name of the simulator that u r using here?

So it was an illusion all along… I finally understand it, thank you.

thank you

I'm surprised that you didn't cover adding an RC low pass filter to get generate a intermediate DC voltage from the PWM signal.

Great Sir and Sir Which Software you are using?Please Reply.Thank You!

good eplanation....

THANKS !

I have a question that I hope you can help me with. I connected a pwm reversible speed controller to my trolling motor. This is supposed to be 100 max and 60 continuous amps. When I first tried it out. I noticed it got fairly hot in the enclosure I made for it so I decided to add a fan. I connected the fan to the 12 v power going in with an inline on off switch. When I tried it,the fan burned out almost immediately. Thinking I may have had a bad fan,I connected a new one with the same result. When I checked the power in with my multi meter,it was showing a very erratic reading. The volts were going up and down from 1 v up to 18 and in between. I even saw it jump to 36 volts. I'm using three 12 volt batteries in paralle. When i checked the voltage at the batteries,it was the same,just all over the place. For the heck of it. I tested the cigarette plug on the jump box that is one of the batteries connected in parallel and low and behold,it was showing the correct voltage which in my case was 13 volts on fully charged batteries. Looking inside the jump box. I notice that the cigarette plug was connected with a small circuit board. I assumed that the circuit board somehow regulated or should I say,normalized the voltage. I ended up running the fan on it's own circuit via the cig plug and it now works fine. The obstacle I'm trying to eliminate is,I also have a 12v steering unit for the trolling motor. I would like to connect the steering unit to the power in of the speed controller as to eliminate having to use another cord but I'm unable to with that type of voltage that it produces. Short of pulling that circuit board out of the jump box,would you possibly know what I can add to achieve this? Also,would you know why this pwm behaves in this manner? Thanks.

PWM Its easy to understand in the synthesiser world because the pulse width actually does modulate usually with the aid of an LFO, however in this instance the pulse width is not actually modulating the time is always the same in every pulse however you could argue the LED is modulation on/off.

How we can amplify that pulsating dc signal? Can you make video on that?

Thankyou sir

Visualizing pulse is funny and interest!

I'm wanting to make a lighthouse for my yard with an LED that fades in and out simulating the rotation of the beacon on a real lighthouse but without needing to actually rotate. I also want to use an 18650 cell or series of cells, and make it solar powered. Do you have any videos that would have a howto where I can make this?

PRODIGY SIMPLY ELECTRONICS 👍 VERY MUCH HELPFUL INFORMATION VIDEO PRODIGY SIMPLY ELECTRONICS FROM NICK AYIVOR FROM LONDON ENGLAND UK 🇬🇧

I don't think I ever learned this in my entire BSEE degree. Thanks for a super simple explanation.

plz , can you tell me what application you present your circuit

Thank u 💜🙏💞😉
