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:

//ellipse(240,400,100,100);
}
float radius;

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.
