Serial Communication Project

I decided to use one of my previous processing sketches and incorporate serial communication into it. The processing sketch I used was my self-portrait. I decided that I wanted to create something that could be used in a party. When the light dims down, the kaleidoscopic-like portrait would fade onto the wall. The project is hyperlinked here. The code I used is incorporated below, I used the handshake technique between processing and Arduino:

Self-portrait:

void setup(){
  size(480,640); //w,h
  frameRate(5);
  
  //fill(255,192,203);
  //ellipse(240,400,100,100);
}

float radius;

void draw(){
  background(0, 0, 0);
  
  fill(0);
  stroke(255);
  ellipse(240,325,730,800);
  stroke(255);
  ellipse(240,325,630,700);
  stroke(255);
  ellipse(240,325,530,600);
  stroke(255);
  ellipse(240,325,430,500);
  stroke(255);
  ellipse(240,325,330,400);
  stroke(255);
  ellipse(240,325,230,300);
  
  
  fill(255);

  ellipse(240,200, 150, 190);
  
  fill(255);
  ellipse(115,350, 50, 80);

  ellipse(365,350, 50, 80);

  ellipse(100,370,5,5);
  
  fill(0);
  ellipse(379,370,5,5);
 
  
  fill(random(0, 204), random(0, 255), random(0, 255));
  ellipse(240,330,275,350); //x,y,w,h

  

  fill(255);
  ellipse(240,360,275,350); //x,y,w,h
  fill(random(0, 255), random(0, 255), random(0, 255));
  ellipse(300,340,75,75); //glasses 1
  fill(random(0, 255), random(0, 255), random(0, 255));
  ellipse(180,340,75,75); //glasses 2
  line(216, 340, 264, 340); //middle portion of glasses
  line(104, 340, 141, 340); //side portion of glasses
  line(336, 340, 375, 340); //side portion of glasses

fill(255);
stroke(0);
arc(240, 410, 50, 35, PI, PI+QUARTER_PI);
arc(225, 410, 20, 20, HALF_PI, PI);

arc(270, 450, 170, 50, HALF_PI, PI);
arc(170, 440, 50, 35, PI, PI+QUARTER_PI);

arc(260, 485, 100, 10, HALF_PI, PI);
arc(260, 470, 50, 30, PI+QUARTER_PI, TWO_PI);
arc(210, 460, 60, 30, PI+QUARTER_PI, TWO_PI);

fill(0);
ellipse(225, 410, 3, 3);

//fill(0);

line(257, 410, 255, 380);


}

Arduino:

bool ledState=LOW;
int knobpin = A1;
int led=3;

void setup() {
  Serial.begin(9600);
  pinMode(led, OUTPUT);
  Serial.write(0);
  
  // put your setup code here, to run once:

}

void loop() {
  if(Serial.available()>0){ //if arduino receving something
    int inByte=Serial.read();//when you read something off buffer, it goes off the buffer
    int readvalue=analogRead(knobpin); //knob
    int writevalue = map(readvalue,0,1024,0,255);
    Serial.write(writevalue);
    analogWrite(led,writevalue);
    delay(1);
  }
    

I wanted to add more elements to this project such as adding music using an mp3 shield once the processing sketch is revealed. I also wanted to add a flex sensor that would simulate a wristband on people. Every time it moved, making the assumption that it moved because they people were dancing, my glasses would start changing color (as it does already). I have had tremendous difficulty coding this, and because I got slightly injured I didn’t have the time to go back and work on this aspect. If I am able to complete my weekly project for this week on time, I really want to spend some time enhancing this project.
