## Introduction: Arduino Self Parking Car Beta

Hi guys! Today, we are going to make a Self Parking Car with Arduino. Let's start!

## Step 1: What We Need?

We will use;

1 - l298n Motor Driver

2 - 1 x Hc-sr04

3 - Arduino

4 - Car Chassis (two motored)

## Step 2: Connections;

Arduino to l298n;

D5 = in5

D6 = in6

D9 = in3

D10 = in4

Other Energy Source = l298n s 12v

WARNING; IF YOU WANT L298N WORK, YOU MUST CONNECT GND PINS EAC OTHER WİTH ARDUINO.

Arduino to Hc-sr04;

5v = Vcc

Echo = 12

Trig = 13

GND = GND

## Step 3: Connect L298n to Car

We use out3 and out4 for forward and backward

We use out1 and out2 for right and left.

## Step 4: How It Will Work?

When car is looking for a parking space, actually it is looking for a parking space bigger than 7cm. If it see smaller than 7cm space, it will continue to looking for bigger than 7cm parking space. Then, when it find a convenient park space, it will go right-forward 5cm and stop,than go backward and steering to left. It will be a perfect car.

Don't forget it is a Beta Version and it can park only left side park spaces. If you have an idea , I will be happy to hear this. Code variables can changeable from car to car. You should organize the numbers. Thanks..:)

## Step 5: Code

You can get the Arduino code there.. I'm waiting for your comments..:)

in code, you are finding the distance which is depth of parking space, but to car get parked we need width of parking space. so car trying to get parked even if width of space smaller than length of car itself. i think we need width of that space. ultrasonic only find depth of space......

the .uno file cant open bro. the error message is could not create the sketch. can u help me to solve this. thx before

#define trigPin 13

#define echoPin 12

void setup() {

pinMode(trigPin, OUTPUT);

pinMode(echoPin, INPUT);

pinMode(5, OUTPUT);

pinMode(6, OUTPUT);

pinMode(9, OUTPUT);

pinMode(10, OUTPUT);

}

void loop() {

long duration, distance;

digitalWrite(trigPin, LOW); // Added this line

digitalWrite(trigPin, HIGH);

// delayMicroseconds(1000); - Removed this line

digitalWrite(trigPin, LOW);

duration = pulseIn(echoPin, HIGH);

distance = (duration/2) / 29.1;

if (distance < 7) { // This is where the LED On/Off happens

digitalWrite(6,HIGH);

digitalWrite(5,LOW);

}

else {

digitalWrite(9,LOW);

digitalWrite(10,HIGH);

analogWrite(6, 110);

analogWrite(5, LOW);

delay(50);

digitalWrite(10,LOW);

digitalWrite(9,HIGH);

analogWrite(5, 110);

analogWrite(6, LOW);

delay(100);

digitalWrite(9,LOW);

digitalWrite(10,HIGH);

analogWrite(5, 110);

analogWrite(6, LOW);

delay(100);

digitalWrite(10,LOW);

digitalWrite(9,LOW);

analogWrite(5, LOW);

analogWrite(6, LOW);

delay(10000);

}

}

looks nice, i would like to see a video of how well it works

A video of it parking, please!

Great effort. Please post a video.
