Accelerometer MPU-6050 marks timeout in Unity
Running MPU-6050 at 57600bps seemed to be the good rate for me:

  pinMode(5,INPUT);
  Serial.begin(57600);
}


It worked for me and I found these guys for whom it was the good rate :

From MPU-6050-simple-library, specifically MPU6050_test.ino:


void setup() {
  Serial.begin(57600);
  MPU6050mgr.begin(); // Initializes IMU module 
}



From Another Arduino as external i2c device for MPU6050:


void setup() {
  Wire.begin(0x1E);                // join i2c bus with address #8
  Wire.onReceive(receiveEvent); // register event
  Serial.begin(57600);           // start serial for output
}



From Library for Arduino and MPU-6050 communication:


void setup() {
  Serial.begin(57600);
  MPU6050mgr.begin(); // Initializes IMU module 
}
