I'm trying out some things on a Udoo (http://www.udoo.org/
), which has an Arduino Due embedded and when I'm plugging in a 10k potentiometer I get a lot of jitter.
In this example http://arduino.cc/en/Tutorial/DueSimpleWaveformGenerator
the circuit for the potentiometer is exactly the same I'm using. But comparing the results of this circuit, to the results of a similar circuit on an Arduino Uno, only supplying the knob with 5V instead, with the Uno the values are very stable (a little bit of flickering of a one value range) and with the Due, it's terribly flickering.
I kind of have the same issue with a Teensy 3.1, which also provides 3.3V. Should I be using a different potentiometer? Can't find enough information on this.
I'm posting here cause Udoo'd forum doesn't provide any answers to this...
