Arduino for Beginners - 2022 Complete Course - Step 1 - Get Distance with Ultrasonic Sensor

This video tutorial guides viewers through setting up an ultrasonic sensor project. It covers defining pins, triggering the sensor, using interrupts for distance measurement, and calculating the distance. The tutorial also includes filtering techniques to ensure accurate readings and concludes with testing the project to verify its functionality.

What is the purpose of the ultrasonic sensor in this project?

What are the two pins defined for the ultrasonic sensor?

Explain how the ultrasonic sensor is triggered in the code.

What is the role of the 'void loop' in the code?

Describe the process of reading the distance from the ultrasonic sensor.

What is the significance of using interrupts in this project?

How does the code differentiate between rising and falling signals?

Explain the purpose of the 'getUltrasonicDistance' function.

How does the code handle erratic sensor values?

What is the maximum distance value that the code checks for?
