2. arduino connect with your pc and open arduino software .

3. copy this program and paste in arduino software

#include <SoftwareSerial.h>
SoftwareSerial mySerial(0, 1);
int ledpin=13;
int Data;
void setup()
{
mySerial.begin(9600);
pinMode(ledpin,OUTPUT);
}
void loop()
{
if (mySerial.available())
{
Data=mySerial.read();
if(Data=='1')
{
digitalWrite(ledpin,HIGH);
mySerial.println("LED On! ");
}
else if (Data=='0')
{
digitalWrite(ledpin,LOW);
mySerial.println("LED Off! ");
}
}
}

4. remove bluetooths rxd and trd wires and upload the programe enjoy...................
