Question

i want the arduino code please

Car Parking Sensor Build a simple Car parking sensor system using the Arduino. Use the provided Ultrasonic Sensor to measure the distance between the sensor and an object. When an object is detected within a defined range, a buzzer must beep repeatedly at a certain rate. And as the object gets closer, the beeping gets faster. Your design must meet the following requirements 1. Calibrate the range of the Ultrasonic Sensor readings using a push button to set maximum and minimum values for the distance. As long as this button is pushed the program shall be in calibration mode. An LED shall be used as an indication for the calibration mode. This can be done at anytime while the program is running 2. An active buzzer shall beep as mention above along with an LED flashing with the beep 3. The defined range shall be divided into three sections. Section 1: 2/3 to max of the range. Section 2: 1/3 to 2/3 of the range. Section 3: min to 1/3 of the range 4. A servo motor shall be used also to indicate the detected distance. It shall move 60°, 120° and 180° when the object is in section 1, 2 and 3 respectively 5. An LCD shall be used to display the following messages Line 1 "Empty Range" when there is nothing in the defined range "Object in Range" when there is an object in the defined range Line 2 "Obj: Far" when the object is in section 1 "Obj: Close" when the object is in section 2 "Obj: very Close" when the object is in section 3 .Any high power component (requires high current) must be driven by an external circuit powered by an external supply variables shall be named properly You can use the serial monitor in the Arduino IDE for debugging purposes The code must be well commented, explaining every part of the code. And The group must show and explain the whole operation of the project in detail .

//PLACEMENT OF PIN ON ARDUINO
#define trigPin 0 //ULTRASONIC TRIG PIN
#define echoPin 1 //ULTRASONIC ECHO PIN
#define blue 10   //LED BLUE PIN
#define red 12    //LED RED PIN
#define green 11 //LED GREEN PIN

//DEFINING PIN MODES
void setup() {
Serial.begin (9600); // begins serial

   pinMode(blue, OUTPUT);
}

void loop() {
// This is where the calculation for the distance of the object happens
long duration, distance; // CREATE VARIABLES

distance = (duration/2) / 29.1;   // CALCULATION TO FIND DISTANCE TRAVELLED BY WAVE USINF TIME,

// This is where the LED On/Off happens
if (distance <= 10) { // if the distance is equal to or less than 10 cm

    digitalWrite(green,LOW);
}


if (distance >= 200 && distance <= 0){ // if the distance is greater than 200 cm or less than 0 cm
    Serial.println("Out of range"); // serial print "out of range"
}

else {
    Serial.print(distance); // display distance on serial
    Serial.println(" cm"); // display units "cm" on serial
}
