Here’s a general schematic of connecting the potentiometers up through a multiplexer into the Arduino.

This allows you to have one scrubber pin which you can read values from and associate it with different physical runs of conductive material (in this case conductive thread).

For my 1and1, I’m building off an older concept of scrubbing through samples with granular synthesis using conductive thread as a linear potentiometer. In the past, I’ve had two conductive ropes connected to power and ground on each end, and a conductive glove in each hand for scrubbing across the rope. This limits the control of the samples to each individual glove. If you switched your hands, the samples would still be attached to the glove itself that is touching the rope, rather than the rope itself seeming to contain the sample.

The goal here is to have multiple “ropes”, and have them each appear to have a sample, while only having one “scrubbing glove”. This is possible through the use of a multiplexer.

Here are two images of a proof of concept with two conductive thread runs. Next I’m going to build out this model to have six or eight of these runs.
