Hi, I'm working on this [u]Magnetic Levitation[/u] project on Arduino where i have to use a mosfet on the pwm arduino pin.
[u]the question is:[/u] why should i use a mosfet insted of any other transistor? The point of using it is that a mosfet can handle a pwm w/ a higher frequency than the others transistors? I'm not sure. Please, help me!!
the schematic bellow isn't mine. I got it from, you know... internet.
