So everything on my automatic lifejacket signal circuit works except I realized that Attiny85 doesn't start interrupts using a +5v signal, it must be pulled to 0v. How would I change this circuit to get achieve this? As stands, when the probes are connected, a +5v is leaving the emitter when the probes are connected. I know I need to use a pull up resistor but i'm not sure how.
