Ok, it worked with a slot bit, but a pot has no stop. The LED lights up when I unplug the 5V line, sometimes the LED flickers even when I plug the 5V back in. If I remove GND, the LED lights up and I can use the potentiometer to set the LED to go out. But I still don't see any moisture displayed. Is the humidity sensor defective or the AD converter?
