Servo: My TUI lego car

After exploring servo motor with potentiometer, I created lego car which moves by servo. I used two tires to make the car mobile and put stick with rubber to the servo motor.

Components:
Arduino
3wires
Servo motor
wooden stick and rubber
Lego blocks

Code: I used reference in Arduino website.(http://arduino.cc/en/Tutorial/Sweep)

// This example code is in the public domain.

#include <Servo.h> 

Servo myservo;  // create servo object to control a servo 

                // a maximum of eight servo objects can be created 

int pos = 0;    // variable to store the servo position 

void setup() 

{ 

  myservo.attach(7);  // attaches the servo on pin 9 to the servo object 

} 

void loop() 

{ 

  for(pos = 0; pos < 180; pos += 1)  // goes from 0 degrees to 180 degrees 

  {                                  // in steps of 1 degree 

    myservo.write(pos);              // tell servo to go to position in variable 'pos' 

    delay(1+1/2);                       // waits 1.5ms for the servo to reach the position

                                 //by doing this I could make the rotation less than 180 degree

  } 

  for(pos = 180; pos>=1; pos-=1)     // goes from 180 degrees to 0 degrees 

  {                                

    myservo.write(pos);              // tell servo to go to position in variable 'pos' 

    delay(1+1/2);                       // waits 1.5ms for the servo to reach the position 

  }
