I am using a Raspberry Pi to turn on a 3.3 output pin, then using Arduino Nano to read a voltage divider. How do I read the voltage in higher resolution (2.131235) than 2.1? The raw analog output is 717-720. The output for my conversionFactor is 0, whether I use int or long. /* Print output for vo…
