Title: PWM???
Post by: methos on March 23, 2008, 21:55:37 PM
This is the last question!

I look the forum and i find an question "How to dim an LED".
The best as i see is the PWM way.

And my question: What is PWM?

Pulse Width Modulation, That is PWM.
In short, is like controlling the speed of a fan, the luminosity of a lamp or led by switching on and off very very fast. If you wait a couple of days i think i can write a more explanatory article about PWM's. :)
