I have a 8.4V fan which spins at around 15k RPM, so it must draw a bit of current. I'd like to switch it on and off from the Arduino, no PWM needed. I'm able to code everything, but I hardly know anything about electronic circuits. I did some searching and am pretty sure the best solution is to do it via a MOSFET? But this is where my knowledge ends, I have no idea on how to choose a suitable one. Could somebody kindly point me in the right direction? TIA.
You need a MOSFET for a logic level. For example, SI2300 is for currents up to 2 amps.
If you're a complete electronics dummy use a MOSFET module or a relay module.
Thank you both. @anon57585045 I wouldn't say complete dummy, but the module might indeed be the easiest way to do it. Would an IRF520 board like this one here do?
I don't like the gate drive on that one. But there are others.
@anon57585045 I found one with an AOD4184, 5-36V, 15A, Arduino compatible. Better?
FYI
