Hi,
I used voltage divider to reduce my sensor to maximum 1.6v so that it is compatible with the ADC but the another problem is the A9 ADC reading in case of no sensor is floating around.
Is there a way to pullup or down in case no sensors attached?
I do not know how to combine both pull down resistor and voltage divider together.
