I want to use a fader as an input on a project I’m working in but I can’t seem to get a stable enough reading from one to make it viable.
The minimum resolution I can goto is 8bit 0-255 and even with this when the fader is set to 50% the readings jump between 125-128.
I’m using a 10K pot and have tried a low pass filter (although I’m not 100% sure of the best value capacitor to use for this).
I also tried hysteresis and smoothing in the software but this made the fader to unresponsive.
I’ve tried using an external regulated PSU and the usb power but I get the same behaviour either way.
What do you normally do to deal with this?
