What is PWM?

In this tutorial I will explain what PWM is and how to control it with the arduino. In one of the future videos I will show how and where to apply pulse with modulation such as controlling motors.
Thanks for watching!

This was truly an amazing explanation, the presentation was so convincing.....

[@thanhhoanginh1381]

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!

[@chalitha22]

Excellent explanation! Keep creating more of them please 🙂

[@eduardomeller6926]

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!

[@NitishDevadiga_Rattle-Snake619]

Thanks for the practical explanation! Really helpful

[@plouf1969]

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.

[@STFocus]

Very basic and understandable presentation ! Thanks

[@yaaro713]

Such a wonderful explanation!! Thanks 😊👍

[@MarkosPoo]

Just incredible video. Thanks for sharing.

[@Mijanur96]

What a video ! Thanks , Thanks a lot for this video.

[@clems6989]

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

[@rahulchowdarypinnaka]

Very nice explanation 👏

[@MaheshPawaskar]

What software did you use to make the animations? Especially, LED brightness, Change in duty cycle of waveform..

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!

pls note it 8-bit varies from 0 to 255

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.

[@djoudigpl8625]

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

[@hariharanvaradarajan5270]

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.

[@Bhupatip]

with 127 that intensity is very low, u can check on dark place...

[@supperslash1376]

I am wanting to know what software you used to make the animations, please?

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

(The good) A good explanation of how PWM works, (the bad) the music is distraction.,

[@bestyav5529]

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

[@freethepotato]

Sure! Thanks for watching.

[@hariharanvaradarajan5270]

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

[@freethepotato]

Hey. You are totally right, if I said that PWM ranges from 0 to 225 i was WRONG.

[@hariharanvaradarajan5270]

No Problem :) Nice Video though..very informative...I am sharing it to my juniors :)

[@sudhansumtripathy]

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.

[@uprajsingh]

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.

[@sudhansumtripathy]

@@uprajsingh 50 MH, so how many PWM do I ned , if I have 4 BLDC and one MC

PWM is used for dimming LEDs and controlling motors

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?
