I'm a noob when it comes to the electronics stuff. I'm trying to wake up Arduino from a low power state via a button press on interrupt 0. I'm doing hardware debouncing with a RC circuit, however it is not triggering on LOW, which I understand is required to wake from a lower power state. It only only seems to trigger on RISING or CHANGE. Do I need to use a Schmitt trigger, or some other hardware changes? Thanks!
