Switch / sleep mode

Projects Programming

hi guys,
I'll explain you what I want to do, I'd like my arduino uno v3 to sleep and wake up when one of my 2 switches get value 1 instead of 0. So I attach interrupt on pin 2 and 3, my sleep mode is : SLEEP_MODE_PWR_DOWN.

The issue is that I don't know if I hase to use pull up, or pull down or another wiring tip.

When I put these 2 switch (+5v, ground to arduino and third wire (green) to my digital pin), my input pin read 0 when the 'door' is closed and 1 when I open it. So I want the pin to wake up the arduino when it goes from 0 to 1.

Any tip to configure my interrupt / pin wiring with the switch ?

Thanks

and wake up when one of my 2 switches get value 1 instead of 0.

Why? It seems far easier to simply wire the switches to match the value that program expects than to rewrite the program to expect different values.

In fact, rewriting the program may not even be possible.

Switches can be wired in pullup mode, or pulldown mode. Adafruit has a good tutorial on switches that illustrates both modes. Use the one that produces values that the program expects.
