Dynamic data to arduino from processing.

ashwini

Can you please tell me if we can send dynamic data to Arduino from processing.. and if yes then in which format? Refering to the slider example.. that my exact application.

Lord_of_the_Galaxy

Please give a proper title to the question, not your name.

As to the question, yes we can. Read this tutorial - https://processing.org/tutorials/electronics/

kfrajer

Please provide a link to your example.

@Kf.. will post it soon..

@lord_of_the_Galaxy.. sorry

Welcome to the forum, @ashwini. You can change the title on your post to something more specific (like "dynamic data to Arduino from Processing") by editing / selecting the gear icon in the upper-right corner.

And you can add the code directly to the question by doing that.

//--------------------------------------ARDUINO CODE-----------------------------------/

char val;

int firstSensor = 0;    // first analog sensor

int inByte = 0;         // incoming serial byte

void setup()

{

  // put your setup code here, to run once:

  pinMode(A0,INPUT);

  Serial.begin(9600);

  eshtablishContact();

}

 

void loop()

{

  if(Serial.available()>0)

    {

      val= Serial.read();

     int T = val;

    Serial.print("val"); Serial.println(val);

//    int tempC = analogRead(A0); //read the value from the sensor

//    tempC = (5.0 * tempC * 100.0)/1024.0; //convert the analog data to temperature in Celcius

//    Serial.println(tempC);

    }

    else

    {   Serial.println("Hello World");

       delay(50);

    }

//the '\n' is our end delimiter indicating the end of a complete packet

  //trim whitespace and formatting characters (like carriage return)
