I don’t have much experience with arduino but I want to create simple project which will control speed of four 2pin PC 12V 0.35A fans with arduino uno. I want to control each fan independently, so each of them will be controlled by own PWM line. I found out that I need to use some sort of NPN Transistor or MOSFET to handle PWM signal to drive single fan.
I do some re-search to find out what will be the best approach for my project but not found clear answear.
Better will be to use TIP120 Darlington transistor with diode protection and resistor or integrated driver module?
