Finals Update #2: The coding is DONE!!!

HORRAY! The coding side of my project is finished! I have to give thanks where it’s deserved: Mimi, Tom, Mathura, Mithru thank you all so much for your help and support.

Here is the final-ish p5.js code (it will include more songs)
let playbutton, stopbutton, nextbutton, backbutton;
let slider;
let fader = 0;
let songBFileNames = ['SpiritInTheSky', 'RunThroughTheJungle', 'HesSoFine','UnderPressure', 'YouNeedLove', 'AmericanGirl', 'SweetLittleSixteen','MaryJanesLastDance', 'BrownSugar', 'LadyMadonna','DontStopTilYouGetEnough', 'TwoPrinces', 'Mmmbop', 'PumpItUp','ObLaDiObLaDa', 'IWontBackDown', 'Taurus', 'TheAirThatIBreathe','PictureBook','TomorrowNeverKnows', 'LittleMermaid'];
let songAFileNames = ['BabyDidABadBadThing', 'TheOldManDownTheRoad', 'MySweetLord','IceIceBaby', 'WholeLottaLove', 'LastNight', 'SurfinUSA','DaniCalifornia', 'WalkAndTalkIt', 'WhatIGot','SteppinOut', 'SemiCharmedLife', 'Unpretty', 'GetOnYourBoots','WhyDontYouGetAJob', 'StayWithMe', 'StairwayToHeaven', 'Creep','SaladDays','LetForeverBe', 'Nude'];
let songAs = [];
let songBs = [];
let albumAs = [];
let albumBs = [];
let currentIndex = 0;
let serial;
let portName = '/dev/cu.usbmodem1421';
let hasStarted = false;
let isPlaying = false;
let volumeA = 1;
let volumeB = 1;
function preload() {
for (let i = 0; i < songAFileNames.length; i++) { songAs[i] = loadSound("assets/sounds/" + songAFileNames[i] + ".mp3"); songBs[i] = loadSound("assets/sounds/" + songBFileNames[i] + ".mp3"); albumAs[i] = loadImage("assets/images/" + songAFileNames[i] + ".jpg"); albumBs[i] = loadImage("assets/images/" + songBFileNames[i] + ".jpg"); } } function setup() { createCanvas(400, 400); background(255); serial = new p5.SerialPort('192.168.1.151'); // make an instance of the serial library serial.open(portName); // open port serial.on('connected', function(){ console.log("CONNECTED"); background(215); }); serial.on('data', gotData); // declare serial data callback function } function draw() { //checkSliderAndUpdateSound(); if(hasStarted) checkFaderAndUpdateSound(); } function checkFaderAndUpdateSound() { console.log("checkFaderAndUpdateSound"); volumeA = map(fader, 0, 1023, 0, 1); volumeB = map(fader, 0, 1023, 1, 0); console.log(volumeA); songAs[currentIndex].setVolume(volumeA); songBs[currentIndex].setVolume(volumeB); tint(255,255); image(albumBs[currentIndex], 55, 20); tint(255, fader/4); image(albumAs[currentIndex], 55, 20); } function playsound() { songAs[currentIndex].loop(); songBs[currentIndex].loop(); } function pausesound(){ songAs[currentIndex].pause(); songBs[currentIndex].pause(); } function stopsound() { songAs[currentIndex].stop(); songBs[currentIndex].stop(); } function nextsetsound() { stopsound(); currentIndex++; if (currentIndex > songAs.length - 1) {
currentIndex = 0;
}
playsound();
}
function lastsetsound() {
stopsound();
currentIndex--;
if (currentIndex < 0) { currentIndex = songAs.length - 1; } playsound(); } function gotData() { let arduinoInput = serial.readLine(); // read an ASCII-encoded string if(arduinoInput.length > 0) {
if (arduinoInput === 'P') {
if(isPlaying) {
pausesound();
isPlaying = false;
} else {
playsound();
isPlaying = true;
} hasStarted = true;
}
else if (arduinoInput === 'B') {
lastsetsound();
}
else if (arduinoInput === 'N') {
nextsetsound();
}
else {
if(arduinoInput == NaN) arduinoInput = 0;
fader = arduinoInput;
console.log(fader);
}
}
}

And the Arduino code:
const int playButton = 2;
const int backButton = 3;
const int nextButton = 4;
int threshold = 2;
const int fader = A0;
int faderValue = 0;
int playButtonState = LOW;
int backButtonState = LOW;
int nextButtonState = LOW;
int prevFaderValue = 1;
int prevPlayButtonState;
int prevBackButtonState;
int prevNextButtonState;
void setup() {
pinMode(playButton, INPUT);
pinMode(backButton, INPUT);
pinMode(nextButton, INPUT);
Serial.begin(9600);
}
void loop() {
faderValue = analogRead(fader);
backButtonState = digitalRead(backButton);
playButtonState = digitalRead(playButton);
nextButtonState = digitalRead(nextButton);
if (playButtonState != prevPlayButtonState && playButtonState == HIGH) {
Serial.println('P');
}
if (backButtonState != prevBackButtonState && backButtonState == HIGH) {
Serial.println('B');
}
if (nextButtonState != prevNextButtonState && nextButtonState == HIGH) {
Serial.println('N');
}
if (abs(faderValue - prevFaderValue) > threshold) {
Serial.println(faderValue);
prevFaderValue = faderValue;
}
prevPlayButtonState = playButtonState;
prevBackButtonState = backButtonState;
prevNextButtonState = nextButtonState;
}

Things I need to fix on the coding side:

  1. When streaming the p5.js sketch to the iphone, you have to press on the iphone’s screen in order to start the sketch, even after you press the physical Play button.
  2. When you start the sketch the album cover from the other side of the slider starts on the opposite side and then suddenly switches to the correct one and acts normally when you move the fader.

Similarity JukeBox

My song comparison box has finally started to come together. Although I haven’t figured out one section of code on the p5.js side that will let the physical fader control not only the sound but the album display, the rest of the functionality seems to be working.

What I hope to convey with this project is how similar two songs can be, using clips of the songs to emphasize exactly what sounds the same between the two.

I’ll be running the p5.js script through an old iphone¬† which will be fastened to the interface shown in the video below. All I need to do is figure out the following:

  1. How to get the songs to play in the order I wanted and not randomly after pressing the next button.
  2. How to map the tint function in p5.js so that the fader works with the album images as well as the song clips.
  3. How to properly fabricate everything so that it fits neatly inside the cigar box.

A p5.js functional sketch version of the project can be seen here.
