Somatosensory game controller

Language:	English  • 中文

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 Module Number Function Microduino-CoreUSB 1 Core board Microduino-10DOF 1 Vector sensor module File:Motion handle.jpg 600px Hardware Buildup Setup 1：Connect CoreUSB to the computer, open program examples, select the right board and serial port, then download the program. Motion_Handle Setup 2：Stack CoreUSB and 10DOF. File:CoreUSB 10DOF.jpg 600px Setup 3：Connect CoreUSB to the computer which will identify a keyboard and display " HID Keyboard Device " in the device manager.

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"); } Judge the controller's motion status. Moving towards left, right, front and back corresponds to the key A, D, W and S respectively. 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); } 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. Video
