Lovely Remote Car

App for controlling the Bluetooth car. The code,circuit diagram and construction of it is in http://lovelyideas.in/arduino.html

code :

int inByte;
void setup()
{
Serial.begin(9600);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);
pinMode(12, OUTPUT);
}
void loop()
{
if (Serial.available() > 0)
{
inByte = Serial.read();
switch (inByte)
{
case '1':
digitalWrite(9, LOW);
digitalWrite(10, HIGH);
digitalWrite(11, LOW);
digitalWrite(12, HIGH);
Serial.println("FRONT");

break;
case '2':
digitalWrite(9, HIGH);
digitalWrite(10, LOW);
digitalWrite(11, HIGH);
digitalWrite(12, LOW);
Serial.println("BACK");
break;
case '3':
digitalWrite(9, LOW);
digitalWrite(10, LOW);
digitalWrite(11, LOW);
digitalWrite(12, HIGH);
Serial.println("LEFT");
break;
case '4':
digitalWrite(9, LOW);
digitalWrite(10, HIGH);
digitalWrite(11, LOW);
digitalWrite(12, LOW);
Serial.println("RIGHT");
break;
case '5':
digitalWrite(9, LOW);
digitalWrite(10, LOW);
digitalWrite(11, LOW);
digitalWrite(12, LOW);
Serial.println("STOP");
break;
}
