Yes. The MOSFET is acting as a switch controlled by the Arduino. Just as with a light switch. When you flip the switch, the lights will come on even though the 120v AC is not passing through you in any way.This is the basic circuit that im looking at, my question is that since the Positive side of the power is not passing through the arduino in any way, will the frequency from the arduino pwm still apply to the HHO generator (motor in this case).
