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.
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 👏
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
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!
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.
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.
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.
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
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
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
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.
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.
Superb explanation and demonstration views, and animations. Congratulations! I think this is the best video in these regards. I will thumbs up, and subscribe.
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.. :)
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.
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
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.
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.
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

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.
I am not an electronic/electrician guy, but your way of explaining is very good. Thanks for your effort 👌
Good job informing, presenting, explaining and linking with sponsors. Thanks.
i have a PWN controller in my house that i use to test DC motors, now i finally know how it works.

You are talent, and thx for help in PWM Understanding, this practical explanation helps a lot. 🤩🤩
Good because speed of words expelling is easy to understand by even non english mothertong peoples. Well planned explanation and good heading

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
nice, im gonna be using this to control the speed of a motor in a smart incubator i´m building. Thanks!
Thanks for this inspiring project!
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..
:)
really hope for other electronic video like this
0:55 Just for clarification, the simplest circuit is a toss up between an open circuit and short circuit.
Wow incredible video! Thank you so much for making this!
perfect explanation and excellent work
The outrun music is perfect.
Great and very educative and entertaining.God bless you

Very good video "keep them coming"
nice work on the circwits
Amazing job, amazing teach, amazing video. Thanks to you man.
thank you for the high quality content
very helpful video to explain the concept in a visual way cheers
Thank you sir very well explained so simple but great impact
Thank you it was a very good circuit. I have question what's the max voltage and amper ?
Great video information 👍
Thank you for sharing your knowledge ❤🇵🇭
Very professional video. Good job!
Plz give information of all components used in pwm with its specifications..
excellent video, thanks for your time
recommend making a timing drumband with the ESP8266 module for motorbikes, the content will definitely be busy,
Good luck with the content👍🙏
i feel that "36 hours of work" per video vibe lol
Very optimum and impressive making.
Thank you very much!
High class video, Thank you 👍
Great job on the animations!

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
Sir please can you answer me a simple dc motor can move by using servo tester and MOSFET?😊
Awesome way to explain it ....thanks
Is there a complete circuit diagram? (from DC in to 12V 4pin PWM FAN connector)
Thanks very much.
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
how about power consumption effeciency of pwm vs switching buck voltage control for motor speed controller?
Excellent video!
Great content, make a video about I2C communication
Thanks for your explaning
that was too good explanation and showed it so easily
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.
thanks for making this video bro
Question how many volts PWM is allowed to enter only 12 v
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).

look proffesional, still i didn't understand what is pwm controller? is a main component around him circuit was built or an special circuit
Nice work bro
But why we don't use power supply to change the voltage. Because of the amperage that can deliver ?
If I have a geared motor that runs at 30RPM, then I add a PWM speed controller, will the max speed still be 30PWM?
D1-D3 number mistake I think D3 is Schottky diode and D1,D2 4148
Great explanation
Good work .
This is an AMAZING tutorial!!!!!!
Sir,
My bldc motor phase voltage uvw.
How can I bldc motor run with two phase wire
Nice project
half way through the video turns into an infomercial
Good work
perfect video man !
Nice video! What program did you use to simulate the circuit diagram?
