Ultrasonic Sensor Functionality

The video tutorial by Koshik demonstrates an Arduino project to measure object speed using Tinkercad. It covers the circuit's functionality, the principle of speed calculation, circuit design, and coding implementation. The project uses an Arduino Uno, a breadboard, and an ultrasonic distance sensor. The code involves setting up variables, calculating distances, and determining speed. The tutorial provides a comprehensive guide to building and understanding the project.

What is the main objective of the Arduino project discussed in the video?

• To measure the temperature of an object
