How to send 2 data to processing from Arduino

Question

I am new to Arduino and processing so sorry for any mistakes. I have a problem with sending multiple data to processing from Arduino. I can send 1 data easily ut I can't send more than 2 data can somebody help?!??. This is my Arduino code:

#include <DHT.h>
#define Type DHT11
int dhtpin =2;
float temopValC;
float temopValF;
DHT HT(dhtpin,Type);


#include <Servo.h>
int servopin=9;
int servopos;
Servo servo1;

int trigpin=10;
int ecopin=11;
float distance;
float spedd=343;
float timee;


void setup() {
Serial.begin(9600);
HT.begin();
delay(200);
pinMode(trigpin,OUTPUT);
pinMode(ecopin,INPUT);

servo1.attach(servopin);


}


void loop() {





 temopValC=HT.readTemperature();
 temopValF=HT.readTemperature(true);

spedd =331.3 +(0.6 *temopValC);
//Serial.println(spedd);

 /*Serial.print("Temp C/F "); //temp val
 Serial.print(temopValC);
 Serial.print("   ");
 Serial.println(temopValF);
 delay (1005);*/





for(servopos=0;servopos < 180; servopos +=1 ){

digitalWrite(trigpin,LOW);
 delayMicroseconds(2000);
digitalWrite(trigpin,HIGH);
 delayMicroseconds(15);
digitalWrite(trigpin,LOW);

timee=pulseIn(ecopin,HIGH);
timee= timee /1000000.;
timee= timee /3600.;

distance= spedd * timee;
distance = distance /2;
distance = distance * 63360;//inch
distance =distance *2.54; //cm
distance= distance *2;

 //Serial.print(distance);
 //Serial.print("  ");
 // delay(200);

  servo1.write(servopos);
  //delay(100);
 // Serial.print(servopos);
  //Serial.println("  ");
   delay(100);
  }
for(servopos=180;servopos >= 1; servopos -=1){

digitalWrite(trigpin,LOW);
 delayMicroseconds(2000);
digitalWrite(trigpin,HIGH);
 delayMicroseconds(15);
digitalWrite(trigpin,LOW);

timee=pulseIn(ecopin,HIGH);
timee= timee /1000000.;
timee= timee /3600.;

distance= spedd * timee;
distance = distance /2;
distance = distance * 63360;//inch
distance =distance *2.54; //cm
distance= distance *2;

// Serial.print(distance);
// Serial.print("  ");
//delay(200);
  servo1.write(servopos);
 //delay(100);
 // Serial.print(servopos);
  //Serial.println("  ");
  // delay(100);
}








/*if(distance < 14.28){
  Serial.println("..............o");
  delay(800);
  }
 if(distance> 14.28){
  Serial.println(" h  ");
  delay(800);
  }

  if(distance== 14.28){
    Serial.println("i   ");
    delay(800);
    }

*/








}

And this is my processing code for one data:

    import processing.serial.*;
Serial mySerial;

String mystring= null;
int nl=10;
float myVal;

void setup(){
size(800, 600);
String myport= Serial.list() [2];
mySerial=new Serial(this,myport,9600);


}


void draw(){

while(mySerial.available() >0){

  mystring =mySerial.readStringUntil(nl);

  if(mystring != null){
  background(0);
  myVal=float(mystring);
  println(myVal); 
  } 
}
ellipse(250,myVal,10,10);
rect(0,0,20,10);
rect(0,40,20,10);
rect(0,80,20,10);
rect(0,120,20,10);
rect(0,160,20,10);
rect(0,200,20,10);
rect(0,240,20,10);
rect(0,280,20,10);
rect(0,320,20,10);
rect(0,360,20,10);
rect(0,400,20,10);
rect(0,440,20,10);
rect(0,480,20,10);
rect(0,520,20,10);
rect(0,560,20,10);
rect(0,600,20,10);

}

I want to change the x value of the ellipse with the second data fromthe Arduino.

Answer 1

If you mean sending multiple integers, floats, or strings, you can use a CSV format.

CSV Format: sentData = variables,variables,variable3

You can then decode it with things similar to substring on the Processing side.
