In some circuits like half bridges and BUCK converters the source of the MOSFET is floating, so not connected to the same ground. I will show 3 circuits built with general components that enable you to effectively drive a floating N-type MOSFET from your Arduino. I will explain how they work, the pro’s cons, simulate all circuits and also build and test the last 2.
