p00kies HC-05 Bluetooth RC Joystick is a simple app designed to control Arduino Bluetooth projects, using the HC-05 Bluetooth Module using an analogue Joystick & 4 buttons on your phone or tablet.
The Data produced by the controls is sent out as a string of integers. Use the following sketch which shows how the data is recieved and sorted.
The Arduino Sketch

}
//Show the incoming Data over local Serial(Debug)//
void showData() {
//Check you have newData to work with
if (newData == true)
{
//Here I'm stupidly reconcatinating the String for your viewing pleasure :D
String output = String(joyX) + "," + String(joyY) + "," + String(btnA) + "," + String(btnX) + "," + String(btnB) + "," + String(btnY);
//Shouting it out over the local serial assuming your testing the Arduino over usb (RX0, TX1)
Serial.println(output);
//And now Clearing the newData flag to start the process over
newData = false;
}
}
//Here's the place holder function with the nessacaries included
void yourFunction(){
//Check you have newData to work with
if (newData == true)
{
//Do your thang here!
//But remember to finish by clearing newData flag
