Driving Relay module with Arduino and MOSFET

[skyhigh123]

I need to modify the below circuit to drive a relay module using a MOSFET and Arduino. I want to drive the relay module with an external power supply instead of arduino pins. I am unable to see the solution. Need help.

I am using an Arduino Nano, a two channel relay module, and my MOSFET is P90NF03L

The question doesn't really make sense.

You would wire the Arduino something like this:

To use that relay with a separate power supply, connect like this:

No MOSFET needed
