Used the force sensor to pause or unpause a video that is being played.

Processing code

 

import processing.video.*;
import processing.serial.*;
 
Movie movie; 
Serial port;
String buf="";
String portname = "COM3";
int cr = 13; 
int lf = 10;  
int waarde;
 
void setup() {
  size(320,240, P2D);
  
  movie = new Movie(this, "cat.mov"); 
  
  movie.loop();
  
  port = new Serial(this, portname, 9600);
}
 
void movieEvent(Movie movie) {
  movie.read();
}
 
void draw() {
  image(movie,0,0);
}
 
void serialEvent(Serial p) {
  int c = port.read();
  if (c != lf && c != cr) {
    buf += char(c);
  }
  if (c == lf) {   
    waarde = int(buf);
    if (waarde > 0)
      movie.pause();
    else
      movie.play();
    println("val="+waarde);
    buf = "";
  }
}
 
Arduino Code
 
int sensorPin = 0;  // select the input pin for the sensor
int val = 0;        // variable to store the value coming from the sensor
 
void setup() {
  Serial.begin(9600);
}
void loop() {
  val = analogRead(sensorPin); // read the value from the sensor, 0-1023
  Serial.println(val);       // writing the value to the PC via serial connection 
  delay(1000);                   // rest a little...
}
