Here I have shown a simple way to measure distance and detect objects using ultrasonic sonar and Arduino. I have mentioned the connection diagram and provided the coding as well. Also I made a video on the topic in DIY style and uploaded to my channel. The video link also is provided in the last step.
Thanks for all the websites where the images are downloaded from.

Step 1: Arrange the Equipment
The Equipment you need are:
1. Arduino (I used a Uno board)
2. Ultrasonic sonar (https://www.ebay.com/p/1pcs-Ultrasonic-Module-Hc-s...
3. Jumper wires (male to female)
4. Computer to read the serial monitor
Step 2: Connection
Connect the wires of the sonar to the Arduino as follows:
Echo Digital pin 10
Trig Digital pin 9
Provide power to the Arduino using usb cable with computer.
Step 3: Coding
Please find the coding in the following link: https://drive.google.com/file/d/1_BWU5w-HfGABOPc2A...
Step 4: Upload and Test
Upload the code to the Arduino and open your serial monitor.
Bring an object near to the sonar and you will see the distance value in centimeters.
The demonstration you can find in the video (at the end of the video) :
