How PWM works | Controlling a DC motor with a homemade circuit

[@memirandawong]

I spent 30 years designing PCB's, beginning with hand taped boards on mylar sheets all the way up to sophisticate auto-routers. Still, It's amazing how far things have come. $2 boards, crazy!

[@jlbleeker]

It’s so enjoyable to finally see an really professional made tutorial. Not only that but also the video is top class. All the kudos to you Sir. Highly recommended.

[@mayacrafts27]

This video is very beautifully completed. Not only great explanation about PWM, but also how to create fully working circuit as well as smooth ads integration. Bonus that nice flow motion time-lapse 👏

[@apfelsafteis]

Seeing the representation on the oscilloscope really helped me understand how PWM works. Thanks for the great demonstrations

[@andrewdavies7845]

Thanks for making this video. I was looking for PWM tutorials mainly for sound processing but this was incredibly informative. Also I didn't realise that PCB's were so cheap to buy, I'll be using those a lot more in my circwits. Many thanks buddy

[@mumin.azraaq]

First time seeing that $30 oscilloscope(Amazon diy oscilloscope) used. Now i'm ordering it. Thanks for using it, and making this video.

[@standforjustice8799]

I learned about pwm from this video and I hardly know anything about electronics. It's thanks to your very good demonstrations. Keep up the work please.

[@Barryd57]

I assembled my first pwm motor controller using assemblies from Amazon. It worked perfectly and allowed my old VW to have AC w/o fixing the defective computer. Thx!

[@TheOfficialDorianelevator]

i have a PWN controller in my house that i use to test DC motors, now i finally know how it works.

[@aminekhelifi837]

You just make the thing enjoy itself. Amazing tutorial! keep this productivity.

[@MamToCos]

I am not an electronic/electrician guy, but your way of explaining is very good. Thanks for your effort 👌

[@MrArcheopteryx]

Very great teacher, you are, Master of the 555. No joke, I learned why we use Pulse Width Modulation with you here and what uses it has. It cleverly limits sordid power dissipation too! Perfect crash course on the 555. Thanks Master. Thanks a lot.

[@srjit_]

Beautifully presented and very clearly explained. Thank you for taking the time and effort to create this video.

[@SkibidiWaPaPaPaPa]

Seriously amazing video with a lot of great info. Thank you so much for making this video. I can't wait make this circuit for myself.

[@genefogarty5395]

From a novice, thank you so much for the tutorial.

[@umargul5644]

Sir,you perfectly explained the pwm,thanks a lot.

[@barneybarney3982]

4:00 for led's we dont use pwm to decrease voltage, same goes for majority of usecases, pwm is mainly use for quick on/off while still having high voltage, just not nonstop, for led or dc motors you need to have high enough voltage to run them at all, so you use time, not voltage to control brightness or speed. Pwm is used for decreasing voltage only for variable voltage output and you need to have inductors and caps on the output, for example VRM for cpu/gpu in pc.

[@dyancatamaran4016]

Good job informing, presenting, explaining and linking with sponsors. Thanks.

[@typxxilps]

pretty late - but I like the way you chose for the PWM explanation. and I like this oscilloscope which I think I will buy to see these pulses and check things like servos. Was not aware of PWM as servocontrol ... Therefore I will walk through the list of videos on your channel to find more explanations I might need later ... really great work this video to do it 3 times from breadbord to pin board to pcb

[@TheMalerdaemon]

0:55 Just for clarification, the simplest circuit is a toss up between an open circuit and short circuit.

[@dalsbury1979]

Excellent video! Very informative, excellent production quality and to the point. Thanks!

[@logandekmarques8412]

I think the analysis in 3:30 is very important. Sometimes you have no option other than use a potenciometer, so sometimes when you work mainly with situations you can't use a PWM, you forget this aspect of the PWM when you have the opportunity to use it 5:16

[@pavankumartidke6906]

Thanks for teaching. Doing electronics is an ART.

[@mohamedz4560]

Good because speed of words expelling is easy to understand by even non english mothertong peoples. Well planned explanation and good heading

Really a good video, simple to understand and clean. Thank you for this tutorial.

[@powegger2]

I like that you showed a website to design and build a pro grade board very nice.

[@rohitsayer1400]

The outrun music is perfect.

[@rciancia]

Thats a good Cir-QUIT

[@Ittybittythetwofacedkitty]

Cir cute

[@anhoanghocgioi3140]

Sir quit

[@jasonspink1981]

The first time I was almost sure I heard it wrong…. The 10th time I was like 😣🙇‍♂️

[@jimmymoughnieh5303]

I hear some people say can you borrow me your car? We are after knowledge not mocking

[@s71402san]

Now that explains why electric multiple unit trains squeak while accelerating or stopping. It's a very primitive VFD. The PWM signal gets sent to the gate/base/control of the switch (transistor), the motor speeds by the average voltage but it in reality is the PWM fluctuations rather than the continuous voltage. Frequencies can be changed for faster speeds or better adjustment.

[@jamaldaraghmeh7009]

You are talent, and thx for help in PWM Understanding, this practical explanation helps a lot. 🤩🤩

[@Danda4inaline]

recommend making a timing drumband with the ESP8266 module for motorbikes, the content will definitely be busy, Good luck with the content👍🙏

[@pariwalatanishq]

Thanks for the video. Was looking for tutorials on PWM for some projects related to RC cars and in general controlling of Motors using PWM.

[@srt4boss1]

I love your channel i learned so ooooo much. I don't hot the like button a lot but i felt compelled to. You are honestly so smart and i look up to you because of videos like this.

[@mktwatcher]

Very helpful. Would you happen to know what the high and low voltages are on the PWM signals used in Volvos to control the AC Blower Motor? Say in a 2008 XC90 there are 2 small awg conductors that must be used for the PWM signals and there are 2 Heavier Wires each 10 Gauge Red and Black that provide power from hot to chasis ground controlled by the power transistor and PWM Duty Cycle Signals. Most literature still uses the term "Resistor Module' that controls AC fan motor speed but that is just from days of the old technology to control fan speeds. The fan control module must be a power transistor instead that is is controlled by the 2 small conductors Blue & Yellow coming from the climate control module.

[@ccv3237]

[@jennierlc2761]

That's a great work of yours sir, but can I ask if how did you design the circuit I mean how did you know the exact value of components to use also how did you know to connect them properly in the schematic, please let me know because I want to learn to design electronic circuits on my own, thank you

[@romans7319]

Great explanation. Thank you

[@lifesaver7866]

Excellent I understand now - as promised

[@bhooshanvijay326]

I don't understand why you used MOSFET while making a Cir-quit with arduino, can't we use a BJT Update: I saw the difference between a mosfet and a bjt. So you can contol the output current with the variable input voltage in a mofet, while in a bjt, you can control the output current using the variable input current. You can generate pwm output in an arduino which will deliver variable input voltage for mosfet and in turn the mosfet will control the current output to the motor or the bulb. Please correct me if I am wrong. I have a doubt: how do you increase the brightness of the led with the current output of the mosfet, I thought increasing the voltage does that.

[@ddmfilmsjaipur]

nice work , how can I use PWM to make DC motor ( pump ) produce pulsatile flow to simulate the pulsation of a human for training purposes
