I have an A1302 hall effect sensor that outputs an analog voltage proportional to the magnetic field. I'm mostly interested on lower field values (of the same polarity) and I'd like to increase sensitivity while decreasing range. I'm thinking about feeding a 2.5V to the AREF pin, which would effective double the resolution over the 0-2.5V range.My question is what happens if the sensor outputs a voltage higher than AREF on an analog pin - will it cap the value, overflow like a variable or burn the ATMega?Don't wanna try before asking for obvious reasons
