Thanks, Jack. I'm not totally surprised. If the voltage from the FSR when not pressed is quite high (eg. 4V) and when pressed is quite low (eg. 2V) then that effectively could be treated as a digital signal, because the digital inputs would have a "transition" zone (around 2.5V) where above that is considered high, and below is considered low.
how do i test to see if the arduino is at sleep or not. ?
