power consumption for input state reading

I am experimenting with interrupts and I want to know if when I use 5v as input to pin 2 to put in state HIGH i am consuming electrical power?
I want to use the LOW parameter for the attachInterrupt command.

Yes as you are when you wire it to ground as a low.
Everything you do consumes power but it is so small it is not worth bothering about.

From the data sheet, input leak current is 1µA maximum, the same whether it is high or low.

So, unless you are doing some extremely low power consumption design, it is negligible as the entire chip will be consuming several thousand times more power.

thank you for your replies!
