    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

  • @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

    • @hariharanvaradarajan5270
      @hariharanvaradarajan5270 6 років тому

      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.
