Hello all! Trying to read a Borg Warner turbo rpm sensor on a digital pin but ran into trouble due to the voltage provided by the sensor, in basic it's spitting out a square 50% wave from 0 to + 5V at a maximum frequency of 6Hz buuuuut it's not 5V. In low rpm it starts as 0.1V and at 200Krpm it's 4…
