is there a way to use it so that current flows between the circuit when there is NO power given to the IC
I thought for a P-FET the current passes through the drain and source until a positive voltage is applied to the gate which breaks the connection between the drain and source?
So technically, when no voltage is applied to the gate, it will act like an closed circuit and when the arduino's digital pin activates the gate, the circuit will be broken?
You could use a depletion mode FET but I think these are rare nowadays, and anyway it will not do what you want.
