The arduino PWM controls the gate of the N channel, which allows the load motor to run.
Now, when you change the PWM, it really just changes the frequency output at the gate of mosfet, and that changes the speed of motor.
So throughout the whole thing, the voltage to the motor remains same.
My question is, when changing PWM does the change the current to the motor and is that why the motor runs fast and slow? If not, is there any way to change the current? Is it possible to have a current changing circuit and pwm, so we have two variables to control?
Any help would be appreciated.
Thank you
