Multilpe variables from Matlab to Arduino

Projects Programming

Hi,
Im trying to send multiple variables from Matlab to Arduino and I cant work it out.

I was succesfull with ONE variable using this guide: How To Send Data From MATLAB To Your Arduino

But unfortunately I cant send MORE of them. I bet it is just simple solution, but i just cant solve it.

Variables I am trying to get are numbers. I was experimenting with Serial.parseInt() but I just cant get it right :confused: can you provide an example in you answer please?

Thank you!

Simple serial code that captures a comma , delimited string from the serial monitor, evaluates the captured String, then operates the arduino LED if the appropriate data has been received.

//zoomkat 3-5-12 simple delimited ',' string parse 
//from serial port input (via serial monitor)
//and print result out serial port
//send on, or off, from the serial monitor to operate LED

int ledPin = 13;
String readString;

void setup() {
  Serial.begin(9600);
  pinMode(ledPin, OUTPUT); 
  Serial.println("serial LED on/off test with , delimiter"); // so I can keep track
}

void loop() {

  if (Serial.available())  {
    char c = Serial.read();  //gets one byte from serial buffer
    if (c == ',') {
      Serial.println(readString); //prints string to serial port out
      //do stuff with the captured readString
      if(readString.indexOf("on") >=0)
      {
        digitalWrite(ledPin, HIGH);
        Serial.println("LED ON");
      }
      if(readString.indexOf("off") >=0)
      {
        digitalWrite(ledPin, LOW);
        Serial.println("LED OFF");
      }       
      readString=""; //clears variable for new input
    }  
    else {     
      readString += c; //makes the string readString
    }
  }
}
