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..:)
