import processing.serial.*;

Serial myPort;  // The serial port

void setup() {
  // List all the available serial ports:
  printArray(Serial.list());
  // Open the port you are using at the rate you want:
  myPort = new Serial(this, Serial.list()[0], 9600);
}

void draw() {
  while (myPort.available() > 0) {
    String inBuffer = myPort.readString();   
    if (inBuffer != null) {
      println(inBuffer);
    }
  }
}
Description Returns all the data from the buffer as a String or null if there is nothing available. This method assumes the incoming characters are ASCII. If you want to transfer Unicode data, first convert the String to a byte stream in the representation of your choice (i.e. UTF8 or two-byte Unicode data), and send it as a byte array.
