ESP32 and digital pot X9C102

No it dosen't need the USB lead. Cut one for nothing. I get the same results with the 5v power supplied to the +5v and Gnd pins on the ESP32. Didn't notice that before. So now back to why dose me touching the metalwork make it work correctly. Strange.

OK got it sorted. (I don't like reading post that have no solution.) I had the output from the two pots totally separate with two wires each, and measured the resistance of each separate pair, and was getting the false readings without touching either the +5v or ground wires or any metal part of the ESP32 really. But what I've done is join one of the digi pots output wires together, So I now have three wires to measure the resistance over, a common and an output from each program. And it works. So now I plan to put it all on a single piece of veroboard and hopefully it will still work.
