Hi I have a PIR sensor which is on a pull down when motion is detected it pulls down to 0.11v and bounces around but is mostly 4.56v. I want to wake the arduino uno up from a SLEEP_MODE_PWR_DOWN mode. The sleep code I have works with a jump from GRD to Pin 2. BUT it doesnt work from the PIR and …

Sleep Interupt Voltages 0.11 to 4.56??
