Ever wondered what PWM is?

[Trez]

I found a very funny and informative series of videos on YouTube that go over some important electronics principles.

Here is the PWM video: http://www.youtube.com/watch?v=Lf7JJAAZxEU

Here is a playlist of videos by the same guy where he goes over some important electronic hardware like diodes, resistors and transistors. http://www.youtube.com/watch?v=-mHLvtGjum4&feature=list_related&playnext=1&list=SP 970BF3F6D77B12E8

Here is another playlist by the same guy: http://www.youtube.com/watch?v=aOJuCYgmPPE&list=PLDE23FAC8A681FA46&featur e=plpp_play_all

I really enjoined these videos and I think you guys will too.
