Arduino car

I have been working on a project that involves controlling a car with an Arduino board. The car is made of a chassis, two motors, and a battery. The motors are connected to the Arduino board through a motor driver, which allows the Arduino to control the speed and direction of the motors using a wii nunchuck as a remote control.

#include <math.h>
#include "Wire.h"
#include "WiiChuck.h"
#include <Servo.h>
#include <RHMotor.h>

WiiChuck chuck = WiiChuck();

int joyX = 0;
int joyY = 0;

#define MOVING_MARGIN 50
#define ROTATE_MARGIN 50

int left_motor_pin = 7;
int right_motor_pin = 6;

RHMotor motor(left_motor_pin, right_motor_pin);

void setup()
{

 Serial.begin(9600);
 Serial.flush();

 Serial.println("Initialize chuck engine.");

 chuck.begin(1000);
 chuck.update();

 delay(1000);

 Serial.println("Completed.");
 Serial.println("Initialize motor engine.");

 motor.start(300);

 delay(1000);
 motor.stop();

 Serial.println("Completed.");
}

void loop()
{

 chuck.update();

 joyX = chuck.readJoyX();
 joyY = chuck.readJoyY();
 //Serial.print(joyX);
 //Serial.print(" ");
 //Serial.print(joyY);
 //Serial.println();

 if (millis()%1000 == 0)
 Serial.print(".");

 if (chuck.zPress() == 1) {
 Serial.println("Z Pressed");
 motor.stop();
 }

 if (joyY > MOVING_MARGIN) {
 Serial.println("Fwd");
 motor.forward();
 } else if (joyY < 0-MOVING_MARGIN) {
 Serial.println("Bwd");
 motor.backward();
 }

 if (joyX > ROTATE_MARGIN){
 Serial.println("Right");
 motor.right(300);
 } else if (joyX < 0-ROTATE_MARGIN) { 
 Serial.println("Left"); 
 motor.left(300);
 }

 if (chuck.cPress()) {
 int left = motor.getLeftServo().readMicroseconds();
 int right = motor.getRightServo().readMicroseconds();
 Serial.print(left);
 Serial.print(" ");
 Serial.println(right);
 }

 joyX = 0;
 joyY = 0;

 delay(20);
}

This is a sort video of the car in action:
