Hello,
I have an homemade sensorbox with a dozen of sliders connected to a Teensy 3.2. I want to use the highest possible ADC resolution but I cannot achieve more than 9 bits without filtering. I have tested several filter types (including the ResponsiveAnalogRead library) and I've had the best results with a median filter.
I would like to improve the the hardware setup. I already have a capacitor between the + and ground on every fader.
What would provide the best results?
1. Power the box with a clean, separate power source instead of the USB?
2. Cover the inside of the wooden box with metal and connect this metal to the ground (shielding)?
3. Connect the sliders to the Teensy over a PCB instead of wires?
Thank you.
