Grumpy_Mike:
In which case have you tried putting a serese resistor of about 20R between the top of the pot and +5V. Then put a 47uF capacitor from top to bottom of the pot. Finally put a 1uF capacitor from the wiper to ground. This would reduce the electrical noise from the pot and give a more stable reading.
Hi Mike,
I have tried smoothing the pot reading by using a running average. You're right - there is jitter on the reading from the pot. It wavers 5 or so clicks even when untouched. Unfortunately, the running average didn't appear to help.
I have not tried using resistors and caps to electrically smooth the reading - I will definitely try this next! The Due actually runs on 3.3V - should I use different cap / resistor values with this in mind? Or are these values pretty standard for this purpose?
