This is the best explanation about PWM I have seen so far. Well done!! Just one little detail that I am sure you know, but came out wrong in the video. At 3:36 you say that the pwm value at 100% is 225, but it is actually 255. I will definitely show your video to my students. Thank you for making it!
One cool way to view the duty cycle is to wave the breadboard fast enough, in the dark, and notice how the LED will not draw a continuous line like it would at 100% duty cycle. You'll probably want to lower the frequency at 100Hz though.
I done the sketch in Arduino. Then added the serial monitor to watch the (pwmValue) numbers. Slowed the delay to 50ms and I can watch the numbers climb from"0" to "255" and reset...Very Cool
Hey man, thank you for the support! You're right, that kind of projects are in my waiting list. Right now I'm so busy with the university I can't make new videos. In a few months, new ones will be coming!
Yeah that's good but it would have been better if you had differentiated the effect of duty cycle on the output voltage and the effect of frequency on the output voltage
@@joaoguilherme5511 I'm trying to find software to do this kind of thing with. That is NOT regular animation software. [DRAW EACH IMAGE ONE AT A TIME]. 😢
Hello thanks for your video.. we are using Pic microchip controller and we need the code for PWM to use with our PIC microchip because. The code which you explaining is just for Aurduino Can you help us? We are using PIC24FJ256GA7
why does the light resets once it reaches maximum brightness? is the does the byte value resets itself or what? nvm, you said it in the video. thanks a lot.
1) Check if youve connected the LED to the PWM Pins of the Uno. The PWM pins are 3, 5, 6, 9, 10, and 11. 2) Check if the LED is working or not. You might be trying the process with a fused LED.
What type of motor is this? 3 pin, one is ground - one is voltage and the third is your PWM. The motor will have specifications of operating frequency.
Thank you. I have tried it and it works. May I film my experiment and upload it to UA-cam - of course linking to your video in my description and giving there all credit to you? Make more videos please.
Sir, I think there is a mistake. The background music is not loud enough, but people can still hear what you are saying. Can you please increase the background music to loud enough so no one should be able to hear what is being said? I think this is a music video not an educational video. So, your voice is annoying.
CANT HEaR YOU OVER THE BACKGROUND MUSIC! I DONT DO DRUGS! are you en educator or and entertainer? do you know the difference! i dont care what type of music you use and nobody else does either! why do you use it?
This was truly an amazing explanation, the presentation was so convincing.....
Thank you! Saw a lot vids about PWM but you are the one who help me truly understand :D
Thank you! Glad you like it!

For the love of god, turn down background music
Jokes on you he doesn't believe in god
@@PiyushSharma-bo6pp replace god with electronics

pls note it 8-bit varies from 0 to 255
Very basic and understandable presentation ! Thanks
Very nice explanation 👏
Bro you are too good just keep making more videos on arduino other projects like obstacles detecting robot etc. You are superb👌

Such a wonderful explanation!! Thanks 😊👍
Thanks for the video. FYI: the background music volume is little bit high, i can barely hear you :)
Thanks for watching! Next time no music :p
What a video ! Thanks , Thanks a lot for this video.
Great video information ❤🇵🇭 thank you for sharing your knowledge ♥️
thank you the most simple Explain in the youtube.
Thanks for the practical explanation! Really helpful
great video tutorial. very easy to understand.❤
Just incredible video. Thanks for sharing.
Nicely done, you don't see bread boards used in videos anymore..
Why didn't you initialize the pwmValue as 0? Does declaring it simply makes it equal to 0 automatically?
really really cool video
What software did you use to make the animations? Especially, LED brightness, Change in duty cycle of waveform..
Which software u have used? Nice animation.
Learned a lot !
Great work kepp it up!
Nice video, thanks :)
Great Information!
Thank you!
(The good) A good explanation of how PWM works, (the bad) the music is distraction.,
I am wanting to know what software you used to make the animations,
please?
Yeah that's good but it would have been better if you had differentiated the effect of duty cycle on the output voltage and the effect of frequency on the output voltage
What software did you use to make the animations (equations, waveform, handwriting, etc)?
Did you ever find out?
@@supperslash1376 Unfortunately not. To be honest I had completely forgotten this comment existed 😂
Well TY at least you replied. :D

Hello man thanks for this video
Thank you🌹.
Excelente 👌
Thank you soooo mcuh!
Thank you 🙏
Kamu sangat membantu saya. Trimakasih
why you need to connect 5 volts, the PWM is already the positive signal? in fact the 5 volts are not connected to anything in your breadboard.
is the PWM value 0 to 225 or 0 to 255 ? coz 8 bits variable can change from 0000-0000 = 0 to 1111 1111 = 255. Pls help
Hey. You are totally right, if I said that PWM ranges from 0 to 225 i was WRONG.
No Problem :) Nice Video though..very informative...I am sharing it to my juniors :)
Are you going to make more?
Thanks man. You're brazuca, right? Haha. Great video!
Thanks! From Portugal but you were close.
I suffer from seizures, do I want pwm or no? I'm confused. What can I do to be able to use my phone and other screens?
What does synchronous PWM mean
why does the light resets once it reaches maximum brightness? is the does the byte value resets itself or what? nvm, you said it in the video. thanks a lot.
How r we supposed to listen to the speaker with background music playing?
I entered your code bet keep getting the warning "function declared implicit int" on line analogWrite?
I'm using MPLab. Please help
in analogwrite=127 this is the half of brightness and the pwm in 50% duty cycle.
why the led not blinking ??
i need answer please
1) Check if youve connected the LED to the PWM Pins of the Uno. The PWM pins are 3, 5, 6, 9, 10, and 11.
2) Check if the LED is working or not. You might be trying the process with a fused LED.
with 127 that intensity is very low, u can check on dark place...
Awesome !
thnx
Hi sir, I have a 24 volt motor with 3 inputs, how many PWM signals is needed, I am not very clear about the PWM and how to control the angle.
What type of motor is this? 3 pin, one is ground - one is voltage and the third is your PWM. The motor will have specifications of operating frequency.
@@uprajsingh 50 MH, so how many PWM do I ned , if I have 4 BLDC and one MC
Great

Great!
PWM is used for dimming LEDs and controlling motors

Sure! Thanks for watching.
please tell me how do you make this animation
It was all done in Adobe After Effects. I use a lot of expressions so I can link animations.
@@freethepotatoAAH OK
I WANT TO MAKE THE ANIMATION THAT YOU DO IN 2:07 IN POWER POINT FOR MY PRESENTATION BUT OK THANKK YOU
Hi. Why 225? Why not 255?
It was a verbal mistake, of course it is 255.
How about pwm in servo ?

Background music is WAY too loud.
