int xValue = Esplora.readJoystickX()+8;        // read the joystick's X position int yValue = Esplora.readJoystickY()+1;        // read the joystick's Y position #include int initx,inity;                                 //declares global variables for inital x/y values void setup() {   Serial.begin(9600);                            // initialize serial communication with your computer   Mouse.begin();                                 // take control of the mouse   initx = Esplora.readJoystickX();               //read initial value for x   inity = Esplora.readJoystickY();               //read initial value for y }

void loop() {   int xValue = Esplora.readJoystickX() - initx;  // read the joystick's X position - initial value   int yValue = Esplora.readJoystickY() - inity;  // read the joystick's Y position - initial value   int button = Esplora.readJoystickSwitch();     // read the joystick pushbutton   int sw1 = Esplora.readButton(SWITCH_DOWN);     // read switch 1 state   int sw4 = Esplora.readButton(SWITCH_RIGHT);    // read switch 4 state   Serial.print("Joystick X: ");                  // print a label for the X value   Serial.print(xValue);                          // print the X value   Serial.print("\tY: ");                         // print a tab character and a label for the Y value   Serial.print(yValue);                          // print the Y value   Serial.print("\tStick Button: ");              // print a tab character and a label for the button   Serial.print(button);                          // print the button value   Serial.println();                              // create a new line   Serial.print("Switch 1: ");                    // print a label for switch 1 value   Serial.print(sw1);                             // print the switch 1 value   Serial.print("\tSwitch 4: ");                  // print a tab character and a label for switch 4 value   Serial.print(sw4);                             // print the switch 4 value   Serial.println();                              // create a new line

  int mouseX = map( xValue,-512, 512, 10, -10);  // map the X value to a range of movement for the mouse X   int mouseY = map( yValue,-512, 512, -10, 10);  // map the Y value to a range of movement for the mouse Y

  if((Esplora.readButton(SWITCH_DOWN) == LOW)        || (Esplora.readJoystickButton() == LOW)){  // checks to see if switch 1 or joystick button is pressed     Mouse.press(MOUSE_LEFT);                     // holds down left mouse button   }   else{     Mouse.release(MOUSE_LEFT);                   // releases left mouse button when not pressed   }

  Mouse.move(mouseX, mouseY, 0);                 // move the mouse

  delay(10);                                     // a short delay before moving again }
