Hello, I want to connect a CPU fan to the Arduino to have a software-controlled ventillator.
My problem is: I do not own something to power the fan with, and the low 5V output isn't that bad of an option, I just need a WORKING fan that just spins and creates a little bit of airflow.
Is it possible to connect the fan directly to the Arduino without breaking it?
Any help appreciated!
No. The Arduino is not designed to power anything more than a few LEDs, and motors create electrical noise that can damage the chips. Always use a separate power supply for motors or servos and connect the grounds.
Hi,
Well, It's Complicated..
You have to know:
The current requirements of the fan at 5V
The current capability of Arduino output pins.
So "almost definitely not"..
But it's an opportunity to learn about Transistors and Resistors and that electronics stuff.
Hi,
Why do you need ventilation for your Arduino, why do you need to control it?
Thanks.. Tom...
