Connie – Final Project

This project features a lovely, be-jeweled turd that talks. The LEDs are synced with the audio to create the illusion that the turd is, in fact, do the talking. I had originally hoped to make this as an example of how people say things that are insubstantial and amount to basically a pile of crap. Though now looking at it the poop seems to become a character of its own – that may one day rise above its state of abject shit and evolve into the most fabulous poo that ever pooped.

The audio file was originally played in processing where the values were then sent to Arduino.

Processing:

import processing.serial.*;
Serial myArduinoSerial;
int valueToSend;

import ddf.minim.*;
Minim minim;
AudioPlayer diatribe;

PImage goldenpoop;

void setup() { 
  size(249, 188);
  goldenpoop = loadImage("goldenpoop.jpg");

  minim = new Minim(this);

  diatribe = minim.loadFile("poopy.mp3");

  float vol = diatribe.getVolume();

  println(Serial.list());

  myArduinoSerial = new Serial (this, Serial.list()[0], 9600);
}

void draw() {

  image (goldenpoop, 0, 0);

  AudioBuffer theBuf = diatribe.mix;
  float vol = theBuf.level();
  float convertedVol = map(vol, 0, 1, 0, 255);

  valueToSend = (int)convertedVol;

  vol = diatribe.getVolume();
  println("volume: " + valueToSend);

  myArduinoSerial.write(valueToSend);
}

void mousePressed() {
  diatribe.rewind();
  diatribe.play();
}

void stop() {
  diatribe.close();
  minim.stop();
  super.stop();
}

 

Arduino:

const int leds[ ] = {
  3, 5, 6, 9, 10, 11};


void setup() {
  // initialize the serial communication:
  Serial.begin(9600);
  for (int i=0; i< 6; i++){
    pinMode (leds[i], OUTPUT);
  }
}

void loop() {
  byte brightness;

  if (Serial.available()) {
    brightness = Serial.read();

    for (int i=0; i<6; i++){
      analogWrite(leds[i], brightness);
    }
  }
}
