Arduino code

Arduino
upload the code into the arduino
#include <Mouse.h>
const int trigpin= 8;
const int echopin= 7;
long duration;
int distance;
void setup()
{
  pinMode(trigpin,OUTPUT);
  pinMode(echopin,INPUT);
  Serial.begin(9600);
 
}
void loop()
{
  digitalWrite(trigpin,HIGH);
  delayMicroseconds(10);
  digitalWrite(trigpin,LOW);
  duration=pulseIn(echopin,HIGH);
  distance = duration*0.034/2;
  Serial.println(distance);
}

processing code

Processing
run this code on processing to plot the disatance
import processing.serial.*;  
Serial myPort;  
String data="" ;
PFont  myFont;  
void setup()
{
