Processing code:
import processing.serial.*;
Serial myPort; // Create object from Serial class
int val; // Data received from the serial port
void setup()
{
size(200, 200);
// I know that the first port in the serial list on my mac
// is always my FTDI adaptor, so I open Serial.list()[0].
// On Windows machines, this generally opens COM1.
// Open whatever port is the one you're using.
String portName = Serial.list()[0];
myPort = new Serial(this, portName, 9600);
}
void draw()
{
if ( myPort.available() > 0) { // If data is available,
val = myPort.read(); // read it and store it in val
}
background(255); // Set background to white
if (val == 2) { // If the serial value is 2,
fill(0); // set fill to black
} else if (val == 1) {
fill (204);
} else {
fill (204, 102, 0);
} rect(50, 50, 100, 100);
}

Arduino code:
// Wiring / Arduino Code
// Code for sensing a switch status and writing the value to the serial port.
int switchPin = 4; // Switch connected to pin 4
int ZZZZ = 7; // Switch connected to pin 7
void setup() {
pinMode(switchPin, INPUT);
pinMode(ZZZZ, INPUT);
Serial.begin(9600); // Start serial communication at 9600 bps
}
void loop() {
if (digitalRead(switchPin) == HIGH) { // If switch is ON,
Serial.print(1, BYTE); // send 1 to Processing
} else { // If the switch is not ON,
Serial.print(0, BYTE); // send 0 to Processing
}
if (digitalRead(ZZZZ) == HIGH) { // If switch is ON,
Serial.print(2, BYTE); // send 2 to Processing
} else { // If the switch is not ON,
Serial.print(0, BYTE); // send 0 to Processing
}
delay(100); // Wait 100 milliseconds
}
Do not workink good. I did mistake in arduino code , but i do not now there. Please help.
