Here's a video of Chris messing with Arduino duty cycles, a fan, and an LED. For more Arduino projects, check out the project: http://www.liquidware.org/view.php?id=75 and http://www.liquidware.com

  • @fadlanfaturrizky94 looks like he's using the duemilanove

  • May I know what kinda Arduino U use.?

  • i dont really see whats so amazing...its a fan and a led...

  • @MCBlakeification yes,

    do some research on N-Mos Transistor and a relay, combining them will let u control even a huge motor if u like

  • would it be possible to power more than one fan? And or larger fans? from an arduino?

  • TheBartTech is right, I just did the math. WELL within safe limits! :D

  • @psp10004 you mean 40 mA. Fans like only use about 0.1 mA on 12V anyway (@1.25W). And I think he's not using any external power so it's running on 5V.

    I don't think this would damage your Arduino. :)

  • Do Not Try This At Home because he is pushing about 60mw trough one digital pin but arduino can only handle 40mw max so if u hook up an led and a fan u will damage your arduino.

  • thank you, I wonder whether the same code will work with an H-Bridge? And also I would like to ask you what the min and max message for the delay in mic.sec are?

    any help appreaciated

  • awsome dude keep it up
