==Objective==
You can control games by the somatosensory analog keyboard--W, A, S and D.

==Principle==
Detect game controller's motion change with three-axis acceleration sensor MPU6050 and then use Microduino-CoreUSB analog function to simulate keys of W, A, S and D.

==Equipment==

==Hardware Buildup==
* Setup 1：Connect CoreUSB to the computer, open program examples, select the right board and serial port, then download the program.
[https://github.com/Microduino/Microduino_Tutorials/tree/master/MCookie_Tutorial/Motion_Handle Motion_Handle]
*Setup 2：Stack CoreUSB and 10DOF.

*Setup 3：Connect CoreUSB to the computer which will identify a keyboard and display " HID Keyboard Device " in the device manager.

==Software Debugging==
Code Description
*Control variable initialization:
<source lang="cpp">
MPU6050 accelgyro; //Three-axis acceleration sensor
int ax,ay,az; //Three-axis acceleration sensor variable
float Ax,Ay,Az;

void setup(){
Serial.begin(9600);
Keyboard.begin(); //Keyboard simulation begins.
Serial.println("Initializing I2C devices...");
accelgyro.initialize(); //Accelerator initializes.
// verify connection
Serial.println("Testing device connections...");
Serial.println(accelgyro.testConnection() ? "MPU6050 connection successful" : "MPU6050 connection failed");
}

</source>
*Judge the controller's motion status. Moving towards left, right, front and back corresponds to the key A, D, W and S respectively.
<source lang="cpp">

void loop() {
accelgyro.getAcceleration(&ax, &ay, &az);
Ax = ax/16384.00; //Calculate X-axis's acceleration
Ay = ay/16384.00; // Calculate Y-axis's acceleration
Az = az/16384.00; // Calculate Z-axis's acceleration
if(Ay >= 0.6 ) //Turn the controller leftwards
{
Keyboard.press('A'); //Keyboard 'A'
}
else if(Ay <= -0.6) //Turn the controller rightwards
{
Keyboard.press('D'); //Keyboard 'D'
}
else if(Ax >= 0.6) //Turn forward
{
Keyboard.press('S'); //Keyboard 'S'
}
else if(Ax <= -0.6) //Turn backward

{
Keyboard.press('W'); //Keyboard 'W'
}
else
{
Keyboard.releaseAll(); //Release the key
}
delay(200);
}

</source>

==Result==
Open NotePad on the computer and connect to Coreusb. By turning the controller leftwards, you'll see the character "A" is printed on the NotePad while by turning the controller back to the original position and you'll see the NotePad stops printing. That also works for the other keys.
