Next task is to make it voice controlled and obstacle detecting bot which i made it , i am just modifying it and making it more simple to present it here… and the code for simple bluetooth car is :-

char data = 0;//Variable for storing received data
void setup()
{
Serial.begin(9600);//Sets the baud for serial data transmission
pinMode(13,OUTPUT);//motor 1 pin 1
pinMode(12,OUTPUT);//motor 1 pin 2
pinMode(11,OUTPUT);//motor 2 pin 1
pinMode(10,OUTPUT);//motor 2 pin 2
}
void loop()
{
if(Serial.available() > 0) // Send data only when you receive data:
{
data = Serial.read(); //Read the incoming data & store into data
Serial.println(data); //Print Value inside data in Serial monitor

  if(data == 'f') // Checks whether value of data is equal to 'f'
    {
     digitalWrite(13,HIGH);   
     digitalWrite(12, LOW);
     digitalWrite(11,HIGH);
     digitalWrite(10,LOW);
    }    
  if(data == 'r') //checks whether value of data is equal to 'r'
     {
      digitalWrite(13,HIGH);
      digitalWrite(12,LOW);
      digitalWrite(11,LOW);
      digitalWrite(10,HIGH);
     }
  if(data == 'b') //checks whether value of data is equal to 'b'
  {
    digitalWrite(13,LOW);
    digitalWrite(12,HIGH);
    digitalWrite(11,LOW);
    digitalWrite(10,HIGH);
  }
  if(data =='l') //checks whether value of data is equal to 'l'
  {
    digitalWrite(13,LOW);
    digitalWrite(12,HIGH);
    digitalWrite(11,HIGH);
    digitalWrite(10,LOW);
  }
  if(data == 's') //checks whether value of data is equal to 's'
  {
    digitalWrite(13,LOW);
    digitalWrite(12,LOW);
    digitalWrite(11,LOW);
    digitalWrite(10,LOW);
  }

}
}
