Arduino for Beginners - 2022 Complete Course - Activity 14 - Solution

The video tutorial explains how to measure the execution time of a line of code using the pulse in function. It demonstrates the process of using micros to get precise time measurements before and after an action. The tutorial also covers verifying the code and interpreting the output, including experiments with sensor distance affecting duration. It highlights the inefficiencies of the pulse in function, especially when used with multiple sensors, and suggests that future lessons will cover alternative methods using interrupts.

What are the potential problems associated with using the 'pulseIn' function in a time-sensitive application?

Discuss the implications of having multiple ultrasonic sensors in a robotic application based on the duration of the pulse.

How can interrupts be used to improve the functionality of the ultrasonic sensor without the delays caused by 'pulseIn'?
