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

[@mezzoedbey3802]

Hey man it doesn't matter how old you are, it's NEVER too late to learn. I wish the best for you friend

[@jess4you13]

You can now make circuits as a hobby

[@maven_grandprime]

Brilliant minds some times flashes at elderly age.

[@hariharanselvaganapathy9832]

Wishing you luck Sir👍

[@industrialautomationkotttu8841]

Great

[@remi00000000]

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.

[@NikholasHolland]

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

[@apananabeel]

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!

[@expansivegymnast1020]

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.

[@StudyWithMentors]

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

[@SimplyElectronicsOfficial]

Thank You :)

[@zozo71zozo71]

yes

[@ShadoDmon]

​@@SimplyElectronicsOfficial is it possible to code an arduino to use a pot for duty cycle and for an adjustable frequency. i want to be able to adjust both on the fly to fine tune a project.

[@brennandc]

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.

[@simonndungu1196]

[@user-rg5mi4nf9p]

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

[@omkarrathore1868]

Thanks - well done

[@abriwin]

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,

[@edwardreichard3852]

I like this explanation

[@mohinishendye1040]

Greatt video Thank you!!

Great job thanks sir very useful thanks

[@DCCTRAINLive]

Very nice! 👍

[@RAGHAVENDRASINGH17]

Great videos

[@psbdavewood]

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.

[@yurkshirelad]

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

[@NaveenKumar-pw2ec]

Excellent ✌️

[@123lightmovies]

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

[@JNDlego57]

Light House Of World It’s a clock. Every electronic circuit needs a clock to beat to, (unless it’s something simple like turning on and off an LED,) just like your body needs a heart to beat too. The cool thing about the 555 is that you can easily change the clock’s frequency by switching out the capacitors and resistors

[@JM_Tushe]

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

[@hafizuddinirham9735]

excellent

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

[@adhamraad8619]

Thank you

[@johnwebb9176]

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 ?

[@jesset-p9225]

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?

[@SimplyElectronicsOfficial]

Any specific SMPS? I already have a video on boost converters. I also have plans to do a video on building a simple Switched-mode regulator. the software is everycircuit.com

[@canecreek00]

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.

[@coolcookie1996]

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

[@phnompenhlifestyle]

hello, may i know what app are you using for this demo?

[@umpy3152]

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.

[@santhoshguru1616]

good eplanation....

[@numsum2225]

Visualizing pulse is funny and interest!

[@pulseboypran]

Thankyou sir

[@MrTamilindian]

Thank u 💜🙏💞😉

[@michaelr6205]

What kind of program are using in the beginning of the video? If you don't mind me asking

[@mostafakamel3865]

Thank u

[@snehashishbanerjee2575]

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

[@helloJobtech]

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

[@Quin.CR7]

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

[@thegreatzoom5073]

Alternating current is already sinusoidal, you don't really need to make it that way. Adjusting its frequency, amplitude, etc. is really pretty fundamental, the real questions start when you're looking into what happens to a circuit when those things change.

[@adriandobrovic1911]

Could you tell me the name of the program ? (simulation)

[@coreacademy6129]

Hi. Which software your used to make this type of circuit like your video
