Pcomp & ICM!

This is the week Physical Computing and ICM merged and blew my mind. The joint lab involves graphing a sensor with serial output. After I finished that, I decided to hook up the camera I used for my Stupid Pet Trick, already wired to a photocell in front of the shutter. My processing sketch takes the reading from the photocell to the diameter of a circle. When the shutter opens, a circle is drawn and then the size of that circle is controlled by the aperture setting on the camera.

The processing code:

import processing.serial.*;
Serial myPort;        // The serial port

void setup () {
size(400, 300);
myPort = new Serial(this, Serial.list()[0], 9600);
}

void draw () {
}

void serialEvent (Serial myPort) {
background(131,175,50);
// get the byte:
int inByte = myPort.read();
fill(0);
noStroke();
ellipse(200,150, inByte, inByte);
}
