Arduino is recommended because it is affordable (costing around 400 to 500 rupees) and versatile, allowing users to create a wide range of projects by uploading custom programs.

What is the purpose of the 40-sensor combo mentioned in the video?

The 40-sensor combo provides a variety of sensors that can be used to create multiple DIY projects, enhancing the flexibility of Arduino-based builds.

What components are needed for the rudder project in the video?

The components needed for the rudder project include an Arduino board, sonar sensors, a servo motor, and a breadboard.

What software is used to program the Arduino in this project?

The Arduino software is used to write and upload the program that controls the sensors and servo motor in the rudder project.

How do you upload a program to the Arduino?

To upload a program to the Arduino, the code is written in the Arduino software, and then it is uploaded directly to the Arduino board via a USB connection.

What role does the processing software play in the project?

The processing software is used to visualize the output from the sonar sensor, displaying information such as the presence of objects and their distance.

What does the red and green line indicate in the visual output?

In the visual output, the red line indicates the presence of an object, while the green lines represent areas where no object is detected.

Why is it important to set the correct COM port in the processing software?

Setting the correct COM port is crucial for ensuring that the processing software communicates properly with the connected Arduino board.

What should you do if the COM port number doesn't match in the processing software?

If the COM port number doesn't match, you should change the setting in the processing software to the correct port number that corresponds to the Arduino connection.
