Sending Strings from Arduino to Processing

Processing Electronics (Arduino, etc.)

If you don’t want to use an array, then you could use something like this:

import processing.serial.*;

Serial myPort;
int counter = 0;
String s1, s2;

void setup() {
  myPort=new Serial(this, "COM3", 9600);
  println("********* end of setup() *********");
}

void draw() {
  String str = myPort.readStringUntil('\n');
  if (str != null) {
    if (counter == 0) {
      s1 = str;
      print("s1:", s1);
      println("====== end of read",counter+1 + " ===========");
    }
    if (counter == 1) {
      s2 = str;
      print("s2:", s2);
      println("====== end of read",counter+1 + " ===========");
    }
    counter++;
  }
}
