No one to help??? how do i get this fault eliminated?

Dear, I try to restore a friends machine, that drives over un-level ground and need to hold a vertical device always perfectly vertical using 1x 12VDC motor. Stabilization is done on 1 axis. Not 2 I believe. His former old friend build a Arduino Uno board with on top a DUALCHANNEL H-BRIDGE motor shield from ELECROW.COM and on top of that board a prototype shield v.5 board containing a GY-521 sensor ( MPU 6050 I believe). We managed to get his old code back via relatives of his former friend who look like this : #include "I2Cdev.h" #include "MPU6050_6Axis_MotionApps20.h" #include "PID_v1.h" // Arduino Wire library is required if I2Cdev I2CDEV_ARDUINO_WIRE implementation // is used in I2Cdev.h #if I2CDEV_IMPLEMENTATION == I2CDEV_ARDUINO_WIRE #include "Wire.h" #endif MPU6050 mpu; // MPU control/status vars bool dmpReady = false; // set true if DMP init was successful uint8_t mpuIntStatus; // holds actual interrupt status byte from MPU uint8_t devStatus; // return status after each device operation (0 = success, !0 = error) uint16_t packetSize; // expected DMP packet size (default is 42 bytes) uint16_t fifoCount; // count of all bytes currently in FIFO uint8_t fifoBuffer[64]; // FIFO storage buffer // orientation/motion vars Quaternion q; // [w, x, y, z] quaternion container VectorFloat gravity; // [x, y, z] gravity vector float ypr[3]; // [yaw, pitch, roll] yaw/pitch/roll container and gravity vector // PID double kp = 20, ki = 0, kd = 0; double Setpoint = 0; // leveled double Input = 0, Output = 0; PID PID1(&Input, &Output, &Setpoint, kp, ki, kd, DIRECT); // ================================================================ // === INTERRUPT DETECTION ROUTINE === // ================================================================ volatile bool mpuInterrupt = false; // indicates whether MPU interrupt pin has gone high void dmpDataReady() { mpuInterrupt = true; } void setup() { // join I2C bus (I2Cdev library doesn't do this automatically) #if I2CDEV_IMPLEMENTATION == I2CDEV_ARDUINO_WIRE Wire.begin(); TWBR = 24; // 400kHz I2C clock (200kHz if CPU is 8MHz) #elif I2CDEV_IMPLEMENTATION == I2CDEV_BUILTIN_FASTWIRE Fastwire::setup(400, true); #endif // initialize serial communication Serial.begin(115200); // initialize DMP devStatus = mpu.dmpInitialize(); // Offsets for calibrating mpu.setXGyroOffset(220); mpu.setYGyroOffset(76); mpu.setZGyroOffset(-85); mpu.setZAccelOffset(1788); // 1688 factory default // make sure it worked (returns 0 if so) if (devStatus == 0) { // turn on the DMP, now that it's ready Serial.println(F("Enabling DMP...")); mpu.setDMPEnabled(true); // enable Arduino interrupt detection Serial.println(F("Enabling interrupt detection (Arduino external interrupt 0)...")); attachInterrupt(0, dmpDataReady, RISING); mpuIntStatus = mpu.getIntStatus(); // set our DMP Ready flag so the main loop() function knows it's okay to use it Serial.println(F("DMP ready!

Thanks for any help. Very welcome when you don't have any arduino experiences !!! Kind regards,
