I don’t understand. The EZeye is connected to AN1 and reports an analog value when queried, from 0 when totally dark to 1023 when very bright. Nothing is connected to AN2 but it doesn’t show 0. It shows a value anywhere from 1 to 1023, it seems to be random. This is using the Utility to read AN2.
As nothing is connected to is why is it returning a value?
