Arduino + Processing Serial Port DATA TRANSFER

Processing Electronics (Arduino, etc.)

Hello,

Are you able to get this to work?

Arduino Code 
float angle;
int count;

void setup() 
  {
  Serial.begin(9600);
  delay(1000);
  }
  
void loop() 
  {
  float x = sin(angle);
  float y = cos(angle);
  Serial.print(count);
  Serial.print(',');
  Serial.print(x);
  Serial.print(',');
  Serial.print(y);
  Serial.print('\n'); //same as Serial.println()
  delay(100);

  angle += TWO_PI/100;
  count++;
  }
Processing Code 
import processing.serial.*; 
 
Serial myPort;    // The serial port
String inString;  // Input string from serial port
int lf = 10;      // ASCII linefeed 
 
void setup()
  { 
  size(400,200); 
  textSize(18);
  
  // List all the available serial ports: 
  printArray(Serial.list()); 
  
  // Open whatever port is the one you're using. 
  myPort = new Serial(this, Serial.list()[2], 9600); 
  myPort.bufferUntil(lf);
  delay(1000);
  } 
 
void draw() 
  { 
  background(0); 
  text("received: " + inString, 10,50); 
  } 
 
void serialEvent(Serial p) 
  { 
  inString = p.readString(); 
  }
