Hello, I'm using voltage division to read the voltage of a 12 volt battery. This gives me a voltage between 3 and 4 volts to an analog pin. But I'm running out of analog pins. I'd like to use a digital pin instead to trigger at say 3.7 volts. Is there a way to set this level using say resistors i…

I think is about 0.6x the supply voltage.
