Automatic Parking Gate

An automatic parking gate project utilizing Arduino involves integrating sensors to detect approaching vehicles and controlling a gate mechanism accordingly. Using an Arduino microcontroller, sensor data is processed to determine when to open or close the gate, ensuring seamless vehicle entry and exit. The project typically includes programming logic for sensor integration, gate control, and potentially a user interface for status feedback. Testing and safety considerations are essential for reliable operation, emphasizing the Arduino's versatility in automation applications.

Code :-

// By Arduino Techy

                                  //

#include <Servo.h>

// constants won't change

const int TRIG_PIN  = 6; 

const int ECHO_PIN  = 7;  

const int SERVO_PIN = 9; // Arduino pin connected to Servo Motor's pin

const int DISTANCE_THRESHOLD = 11; // centimeters

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

// variables will change:

float duration_us, distance_cm;

void setup() {

  Serial.begin (9600);       // initialize serial port

  pinMode(TRIG_PIN, OUTPUT); // set arduino pin to output mode

  servo.attach(SERVO_PIN);  

  servo.write(0);

}

void loop() {

  // generate 10-microsecond pulse to TRIG pin

  digitalWrite(TRIG_PIN, HIGH);

  delayMicroseconds(10);

  digitalWrite(TRIG_PIN, LOW);

  // measure duration of pulse from ECHO pin

  duration_us = pulseIn(ECHO_PIN, HIGH);

  // calculate the distance

  distance_cm = 0.017 * duration_us;

  if(distance_cm < DISTANCE_THRESHOLD)

    servo.write(90); // rotate servo motor to 90 degree

  else

    servo.write(0);  // rotate servo motor to 0 degree

  // print the value to Serial Monitor

  Serial.print("distance: ");

  Serial.print(distance_cm);

  Serial.println(" cm");

  delay(2000);

}
