I have a 5 volt brushless 3 fase motor (fan) from a graphical card. What's the simplest way to make the motor go left right and change the speed.
What worked somewhat is just connecting it like a stepper motor. With the Arduino tutorial. I just can't get the speed controlled nor the direction. What I've also tried is with the L293 H bridge but that didn't do anything.
Is there a simple way to such a thing? I've worked with regular dc motor in the past and then I could do a somewhat equal thing with the pwm output. But that wasn't so accurate, is it possible that it's the same with a brushless?
