Circuit Skills – PWM – Pulse Width Modulation

Pulse Width Modulation is an easy method for controlling analog devices with a digital signal. It is a great way to control LEDs, lamps, motors, and more.

  1. what is inside of the pulse generator? I want to know the process of tuning and how it is possible.

  2. The description of this Jameco part is not clear how you control the duty cycle . . .?
    so a modulated signal is needed to control a modulated signal?

  3. This kit does the opposite of what I needed recently, where I needed to convert a PWM signal into a linear DC voltage.
    Basically a Low pass filter and voltage follower…..

  4. can i control stepper motor with this board? If anybody has expriance pleas let me know thanks

  5. 1. you made me laugh
    2. I will never forget the meaning of PWM
    3. I will control the motor speed without a resistor
    4. you are kinda awesome
    5. Not kinda but comprehensively awsome

  6. his faces are pretty wild man this dude its FULL of herself but then again his friends with the aidafruit team so i guess this explains

  7. .
    Well done – a very good Tutorial.
    Compliment for the "Tutorial-Man": Good job.
    I like it, how he explains it.

  8. Soo ? if you can adjust the input voltage then why do you need the PWM? And what do you use to adjust the input voltage? another PWM? 

  9. The Book on his desk is called "The art of Electronics". Its a really good electronics book if anyone is looking for one!!

  10. saludos de guayaquil ecuador estoy interesado en el producto circuit skills pwn  part 120539  mi celular  es 0999557511   favor indicar forma de pago tiempo de entrega
    necesitamos ver la calidad primero, para importar  200 unds.

  11. I want what he is smoking…
    You didn't mention the greatest benefit of PWM, it is very efficient compared to dumping energy through a resistor.
