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!
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.
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!
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 👏
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.
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
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.
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.
so, i just tested the signal generator on my oscilloscope and measured it against a potentiometer. it doesn't change the duty cycle, but does change the amplitude of the pulses
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
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
on the lighter side, certainly funny. But we all have accents, even native born! the way the brits make fun of Americans.. and Indians make fun of the Brits and the Americans.. :)
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.
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.
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.
Hi, is there a wiring diagram of the Arduino that you created near the end , I'm currently running a project , however, I have to show examples of each a mechatronic motor, a plc motor and a pmw, that one you placed at the end is perfect for what I need to do, many thanks, great video 👍
Good job and a nice implementation. I'm gonna to fo Mosfet driver and I want a high frequency typically like 50khertz. Can the Arduino give me these values or I have to implement a timer 555 and deal with resistors and capacitors to have these frequencies
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
Doesn’t the mosfet in the schematic need a pull down resistor to drain gate capacitance? Otherwise the mosfet will be in saturation mode for a long time.
Superb explanation and demonstration views, and animations. Congratulations! I think this is the best video in these regards. I will thumbs up, and subscribe.
Excellent video. How did you learn to design PCBs on Easyeda? There are no good videos from them. Also looking for components and picking the correct size, for example to fit a POTs pins is like searching through a jungle. How do you determine correct pin spacing on components contributed by other people? Any helpful tip is much appreciated. Keep up the great work. Thank you.
Noob question perhaps... but why is it simply assumed that voltage applied for less time AUTOMATICALLY equals lower voltage? Does it require a specific component to perform the averaging (e.g. capacitor?)? Or is it always true in any circuit (even more interesting why)? Does it perhaps require some component to not be there (RC filters come to mind)?
Hello I have unusual question wuld that circuet work with pick up coils found in distributors? I have for days problems finding corect circuet to interupt pick up coils going to ignition module . So any help please? Basicaly I need circuet that can control pick up coils phase shift them or controling pulse generators pulse duration
Is there a way you can make the circuit so that instead of using Variable Speed, you use 3 Speeds within the motor instead? For example instead of the potentiometer using the Variable Speed to control the motor using 3 Speeds within the motor shaft instead of customizing it from an Aesthetic Low Speed (very slow) to Full Blast/Super High Speed (very fast).
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.
Hi. This is a great video. The best visualization of the content I've seen so far. A bit old, but I hope you still can see this message. Regarding the circuit representation about 5:30, with the small waves next to the components, did you get inspired by some software? I'm very interested in making some visualizations of this kind for learning.

First time seeing that $30 oscilloscope(Amazon diy oscilloscope) used. Now i'm ordering it. Thanks for using it, and making this video.
I am not an electronic/electrician guy, but your way of explaining is very good. Thanks for your effort 👌

i have a PWN controller in my house that i use to test DC motors, now i finally know how it works.
Beautifully presented and very clearly explained. Thank you for taking the time and effort to create this video.
Good job informing, presenting, explaining and linking with sponsors. Thanks.

Sir,you perfectly explained the pwm,thanks a lot.
You just make the thing enjoy itself. Amazing tutorial! keep this productivity.
so, i just tested the signal generator on my oscilloscope and measured it against a potentiometer. it doesn't change the duty cycle, but does change the amplitude of the pulses
Good because speed of words expelling is easy to understand by even non english mothertong peoples. Well planned explanation and good heading
Thanks for teaching. Doing electronics is an ART.

I like that you showed a website to design and build a pro grade board very nice.
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
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.
0:55 Just for clarification, the simplest circuit is a toss up between an open circuit and short circuit.
This video taught me new words:
Mobulation
Sirquit
Axzilloscope
Vinary
Viaring
Modar
Lmao
on the lighter side, certainly funny. But we all have accents, even native born! the way the brits make fun of Americans.. and Indians make fun of the Brits and the Americans..

Plz give information of all components used in pwm with its specifications..
nice work on the circwits

Good job and a nice implementation. I'm gonna to fo Mosfet driver and I want a high frequency typically like 50khertz. Can the Arduino give me these values or I have to implement a timer 555 and deal with resistors and capacitors to have these frequencies
very helpful video to explain the concept in a visual way cheers
perfect explanation and excellent work
Amazing job, amazing teach, amazing video. Thanks to you man.
Thats a good Cir-QUIT
😂😂😂
Cir cute
Sir quit
The first time I was almost sure I heard it wrong…. The 10th time I was like 😣🙇♂️
I hear some people say can you borrow me your car? We are after knowledge not mocking
This was awesome and engaging! Keep them coming!
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
Wow incredible video! Thank you so much for making this!
Great video! Very informative and easy for a noob like me to comprehend :)
look proffesional, still i didn't understand what is pwm controller? is a main component around him circuit was built or an special circuit
Great video. This was extremely helpful!
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

You deserve more than a like for this great work 👍
Much appreciated!
High class video, Thank you 👍
that was too good explanation and showed it so easily
thank you for the high quality content
Sir please can you answer me a simple dc motor can move by using servo tester and MOSFET?😊

Nice video! What program did you use to simulate the circuit diagram?
Hi from Argentina, excellent video, i have a question, can i use this pwm to control volume of alarm siren 12v?
Very professional video. Good job!
Very good video "keep them coming"
Thanks for your explaning
Awesome way to explain it ....thanks
how do you create these animations. I'll really appreciate if you can share this.
If I have a geared motor that runs at 30RPM, then I add a PWM speed controller, will the max speed still be 30PWM?
Noob question perhaps... but why is it simply assumed that voltage applied for less time AUTOMATICALLY equals lower voltage? Does it require a specific component to perform the averaging (e.g. capacitor?)? Or is it always true in any circuit (even more interesting why)? Does it perhaps require some component to not be there (RC filters come to mind)?
But why we don't use power supply to change the voltage. Because of the amperage that can deliver ?

I would like to see you make one that can handle 45 amps motor controller
hi , thanks for the video , found the link from easyeda
Good video! Can I use an LED instead of a motor? If so, can I consider it as a constant current driver or voltage driver? Thanks
how about power consumption effeciency of pwm vs switching buck voltage control for motor speed controller?
Thank you very much for you. god bless you!

Do you lose torque with lower speed as much as you would if you were to use a simple potentiometer to lower the voltage?
half way through the video turns into an infomercial
Please what is the name of the program you did the circuit simulation in?
Excellent video!
