I am using voltage regulater IC 7805 to give supply to arduino but it gives higher current supply.I want to know the internal resistance of atmega 328 so that I use resistance in between the digital pin and 7805 to lessen the current

internal resistance of atmega 328

Ohms law doesn't apply to active devices, in general.

They don't obey the laws of physics?
