    Hello! right now i would like use two Potentiometer to control different things. The first I just use the code from example”Analog Inout”. And i when want read the number of another potentiometer in same way. That don’t worked anymore. Besides after i write new code, console.log() or basically oder like $(‘#poti2’).text(“poti2 = ” + valueIn.toFixed(0)); don’t worked any more either. My board is Arduino Uno, laptop running on mac system. I hope someone can tell me, where is the mistake from my code. thanks!

    followed is my code
