Knitting city noise is a part of the Project that may or may not be made

I want to connect a digital knitting machine (that has a small computer inside of it) to a sound sensor. This sensor will react to the sounds around it (city noise) and switch the colour of the yarn that is being used, creating a distinct fabric for each event that is being listened to.

This could be done by placing the sensors in different locations, listening to the sounds of the city and looking at the codes and machines interpretation visually translated into a fabric. Using the fabrics to imagine what city experience they refer to, heavy traffic, the sound of a tram passing by, a metro announcement, wind between tall buildings, loitering, construction etc.

The ideal outcome for this would be showing the fabrics in an installation setting, showing the fabrics possibly in connection to the sounds they come from.

Why make it?

Making a visual output to city noise. Looking at noise, mixing two senses and trying to capture the sonority of being in a busy city, and how the machine perceives it through a visual output.

Also on a more personal objective perspective, practising using arduino and sensors, connecting my interest for garment making techniques and fabrics with technology

Workflow

Identifying and choosing city noise. Researching and learning about how digital knitting machines work, more specifically, looking at the brother electroknit kh-940 since it is the one available to me in the fashion station. Based on my findings, programming the code for the sensor to listen and then change the colour of yarn when it hears noise. Testing the results on the machine, making adjustments on the sensitivity of the sensor. Knitting several different fabrics based on different city noise and observing the differences between them.

Timetable

Two maybe three weeks? I feel like once the code works it should not take long to put together. It is not that ambitious of a project I think.

Rapid prototypes

Connecting the sound sensor (from prototyping class):

#define VCC 5.0
#define GND 0.0
#define ADC 1023.0
const int sensorPin = 34;
float voltage; 
void setup() {
 Serial.begin(115200);
}
void loop() {
 voltage = GND + VCC*analogRead(sensorPin)/ADC;
 Serial.println(voltage);
}

Previous practice

My practice often references and includes elements from fashion and fabric manufacturing techniques.

Relation to a wider context

Does machine find the city overwhelming? or does it find it soothing? how can this be interpreted by simply looking at fabric?
