Making a Game With Arduino and Processing -

i trying form 2 player game requires audio reflex visual. using littebits sound trigger sound input , littbits arduino connect computer. new , don't know how connect arduino processing , use input sound trigger effect score when black square appears.

here code in processing , sample arduino code have taken littlebits website , tried modify little.

thanks in advance!

you need 2 pieces of code work: 1 on arduino sends commands, , 1 processing receive , parse commands.

i haven't used littlebits modules, here's button example this detailed tutorial.

arduino code:

int switchpin = 4;               // switch connected pin 4   void setup() {    pinmode(switchpin, input);     // set pin 0 input    serial.begin(9600);            // start serial communication @ 9600bps  }   void loop() {    if (digitalread(switchpin) == high) {  // if switch on,      serial.print(1, byte);               // send 1 processing   } else {                               // if switch not on,     serial.print(0, byte);               // send 0 processing    }    delay(100);                            // wait 100 milliseconds  } 

and matching processing code:

import processing.serial.*;   serial port;            // create object serial class  int val;                // data received serial port   void setup() {    size(200, 200);    framerate(10);     // open port board connected   // , use same speed (9600bps)    port = new serial(this, 9600);  }   void draw() {    if (0 < port.available()) {        // if data available,     val = port.read();               // read , store in val   }    background(255);                   // set background white   if (val == 0)  {                   // if serial value 0,     fill(0);                         // set fill black   } else {                           // if serial value not 0,     fill(204);                       // set fill light gray   }    rect(50, 50, 100, 100); }
