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?

Hello,

 

The potentiometers do not turn even with the smallest Phillips screwdriver (CRV 1.0). Could it be that these pots are defective?

Today I connected valves, they switch well, but there is no visible activity on the A2D converter. It's not clear to me how I'm supposed to turn these mini little pots

And another question. Yesterday I plugged my OSPi into my Raspberry 3b+. A top-hat rail power supply with 24vAC output was plugged into the OSPi board and my Pi turned on too. Is that normal? I thought I had to supply the PI with extra power. In addition, no lamp on the AD converter was lit. And yes, I am 100% sure that it is a power supply with AC on the secondary side is https://www.amazon.de/gp/product/B00F4QFH4O/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

What else could I have done wrong?

[Dirk Hildebrand]

Yes, precisely summarized, but how do I incorporate this into a program? And if the moisture sensor says “moist”, the watering should also stop if you don’t put the sensor right next to the drip hose, right?
