I have the simple Potentiometer Setup as in the Arduino basic tutorial.
But the values i get dont vary with moving the potentiometer.
they are noisy wit uploading the sketch and then stabilise sometimes around 170 sometimes around 120
Using a Photosensor i had the same Problem
the values stayed stiff around 170
the less light there was the more noisy it got until ranges between 230 and 100
anyone an idea where this values come from?
there could also be a problem in the code but i guess its any mechanical issue
what do you say?
