Arduino Self-Driving Car Lesson 4: Using the Ultrasonic Sensor

The video tutorial covers the use of ultrasonic distance sensors, specifically the HCSR 04, in Arduino projects. It explains the wiring and programming of the sensor, using Tinkercad for simulation and testing. The tutorial also discusses real-world applications, challenges, and experiments to understand sensor accuracy and functionality.

Discuss the importance of understanding the sensor's data sheet.

What are some factors that can affect the accuracy of the ultrasonic sensor readings?

What experiments can you conduct to test the ultrasonic sensor's effectiveness?

How can you modify the code to include an LED that indicates when an object is detected?
