i have a PWN controller in my house that i use to test DC motors, now i finally know how it works.
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
Seeing the representation on the oscilloscope really helped me understand how PWM works. Thanks for the great demonstrations
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 👏
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.
You just make the thing enjoy itself. Amazing tutorial! keep this productivity.
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.
Thank you for teaching me more about the possibilities. I am designing fan controls for inexpensive gasifiers we are delivering to poor farmers throughout Laos, Cambodia and Vietnam. I am the goto electronics technician on this endeavour. Great video. 👍
Really a good video, simple to understand and clean.
Thank you for this tutorial.
Good job informing, presenting, explaining and linking with sponsors. Thanks.
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.
Beautifully presented and very clearly explained. Thank you for taking the time and effort to create this video.
Excellent video! Very informative, excellent production quality and to the point. Thanks!
Sir,you perfectly explained the pwm,thanks a lot.
First time seeing that $30 oscilloscope(Amazon diy oscilloscope) used. Now i'm ordering it. Thanks for using it, and making this video.
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.
This was awesome and engaging! Keep them coming!
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!
You are talent, and thx for help in PWM Understanding, this practical explanation helps a lot. 🤩🤩
Really great content with quality and knowledge. Thanks for sharing your knowledge and creativity.
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
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.
Great video keep up the good work. Helped me understand PWM.
I am not an electronic/electrician guy, but your way of explaining is very good. Thanks for your effort 👌
the presentation and explanations are very nice and clear, thanks for such an video.
one of the best videos of this subject that i have seen
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!
very helpful video to explain the concept in a visual way cheers
Wow incredible video! Thank you so much for making this!
Thank you so much for making such a wonderful informative content. I really appreciate your effort. Keep making such videos.
From a novice, thank you so much for the tutorial.
Thank you sir very well explained so simple but great impact
Good because speed of words expelling is easy to understand by even non english mothertong peoples. Well planned explanation and good heading
This is an AMAZING tutorial!!!!!!
Great video! Very informative and easy for a noob like me to comprehend :)
perfect explanation and excellent work
Great job on the animations!
Thank you so much for your electronics videos.
Superb explanation and demonstration views, and animations. Congratulations!
I think this is the best video in these regards. I will thumbs up, and subscribe.
nice, im gonna be using this to control the speed of a motor in a smart incubator i´m building. Thanks!
Very good video "keep them coming"
Great video information 👍
Thank you for sharing your knowledge ❤🇵🇭
Great video. This was extremely helpful!
Thanks for sharing this useful information.
thank you for the high quality content
Very professional video. Good job!
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.
You deserve more than a like for this great work 👍
Much appreciated!
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.
Amazing job, amazing teach, amazing video. Thanks to you man.
Thanks for your explaning
that was too good explanation and showed it so easily
Great and very educative and entertaining.God bless you
Great explanation. Thank you
Thank you it was a very good circuit. I have question what's the max voltage and amper ?
thanks for making this video bro
excellent video, thanks for your time
really hope for other electronic video like this
nice work on the circwits
Thanks mate, very useful video!!!
The outrun music is perfect.
Great explanation
Do u 've any suggestion for higher frequency about 1Mhz.. while looking through a camera my flood lights are flickering in full efficiency
Thank you very much for you. god bless you!
Excellent I understand now - as promised
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
great explanation
hi , thanks for the video , found the link from easyeda
perfect video man !
Nice work
Nice work bro
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 👍
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.
Excellent video!
Just brilliant
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.
Awesome way to explain it ....thanks
Nice video! What program did you use to simulate the circuit diagram?
Very optimum and impressive making.
Thank you very much!
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
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
Nice project
Excellent video.
Great quality training videoI could understand ....
Good work
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
Thanks man!
Very good video, thanks.
Hi from Argentina, excellent video, i have a question, can i use this pwm to control volume of alarm siren 12v?
Good work .
Very inspiring!
Great content, make a video about I2C communication
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.
good job ! keep going
Nice very helpful 👍
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
Excellent . Thanks
