PUPPET CONTROLLER

Step 3 Mouth on computer screen

Now lets make a 'virtual' version.  This will show an animated 'mouth' on the computer screen.  For now I just want to get something working, so this code uses the X value from the mouse to determine the angle of the mouth opening.  Latter we'll jam the value form the flex sensor in here.

This uses Processing (from www.processing.org)  

//PROCESSING CODE
//pacman moouth opens/close with X input from mouse

float x = 0;
float val = 0;

void setup(){
size(200,200);
background(100);
smooth();
}

void draw(){
background(100); //clear last image
val = mouseX;
x = map(val,0,200,0.01,0.3); //translate values input to useful values
println(x);
arc(100,100,50,50,(x)*PI,PI+(1-x)*PI); //draw packman, using radians... p21

}
