Topic: Arduino powered fan (Read 614 times) previous topic - next topic


I don't think an arduino digital pin has enough power to drive a fan, however small. A direct connection would risk frying the chip.


Can you guys out there please help?

The Arduino won't "power" a fan. It could control it, via suitable hardware. But in this case it seems you're planning to control it via a switch. I don't see any need to use an Arduino for what you're trying to achieve.
I only provide help via the forum - please do not contact me for private consultancy.


I meant like a temperature-controlled switch. And how would I set up the fan to external power so I don't fry the Arduino


Is there something else you're not telling us about your project ? :D

Have you tried searching the forum for things like "fan control", "pwm fan" ?


No. I just figured I would post something to ask people's advise
