Sewing a Circuit

Three Digital Switches

Here I made a pad that has three digital switches sewn into it, while all three do work, I only have two pairs of alligator clips so in the video below there are only two or the three connected to the Arduino, and I’ve made a fourth switch out of copper tape that I videoed separately.

The three-button switch is a little finicky and I think it’s due to there not being enough space in between the two sides of conductive fabric, so every now and again they are still making contact even when not pressed.

For the copper tape switch, I put a strip of copper tape on the back of my TV remote so that it could turn the LED on or off when placed between the two strips.

Analog Sensor

Below is a picture of two sensors, and a video of one displaying the values in the Arduino’s serial monitor. I’ve noticed that with the analog sensors it is quite sensitive to touch, so the value range goes from 0 to 1023 quite quickly.

Final Prototype

For my final prototype, I’ve made three analog sensors to be used with my P Comp project that controls a P5 sketch.

In the video below, I have four analog sensors hooked up to an Arduino Nano on a breadboard. I have a potentiometer that controls the max size of the ellipses on screen, one of the textile sensors controls the R value and another the B value of the stroke() color, and the third sensor controls the step size or density amongst the ellipses.
