So I've been using the soil sensor with my Uno. I've managed to make it work with the digital pin however I'm trying to use the analog pin.
When I connect everything and upload the code and open up the Serial Port, it shows the same value always not matter what. When I connect it to A0, it shows 15. at A1 it shows 16, at A2 it shows 17 etc. Nothing changed when I dip the ends in water or not (same with soil, rather than water).
Is my analog pin not working or is this a typical problem?
