5V MOSFET for Switching on/off Servo

Other Hardware General Electronics
1

Hello,

I have an arduino nano, 5v 3A power supply, 60V/30A N-channel MOSFET, and small hobby grade servo. My goal is to run the servo from the arduino, but effectively power it off when not in use. This is because my device needs to run for long periods without use of the servo and I would rather it not stay powered since this can degrade it quickly. Since the servo draws more than an Arduino digital pin can output, I can't hook the servo 5V line up to an arduino digital pin. Instead, I need to power it from the power supply directly. How (if possible) can I wire up the MOSFET so that it can switch on (5v) or off (0v) the servo through writing a digital pin on the arduino?

A P channel high side switch would be better.

There is no advantage in using a high side switch.

@OP: what MOSFET do you have? Not all can be controlled by 5 V.
