Arduino for Beginners - 2022 Complete Course - Get the Time with millis() and micros ()

This video tutorial explains how to use time functions in Arduino, focusing on the Millis function to get the current time since the program started. It covers the use of unsigned long data types to store time values, best practices for naming variables to avoid conflicts, and demonstrates how to print time using the serial monitor. Additionally, it introduces the Micro function for more precise time measurement in microseconds.

What does the Millis function in Arduino return?

• The time in seconds since the program started

• The current date and time

• The time since the Arduino was powered on

• The time since the program started

Why is the unsigned long data type used to store time values from Millis?

• Because it can store characters

• Because it can store only positive numbers

• Because it can store decimal numbers

• Because it can store negative numbers

What should you do if a variable name turns orange in the Arduino IDE?

• Use it as a function name

• Ignore the color

• Change the name to avoid conflicts

• Use it as it is

What happens when you press the reset button on the Arduino?

• The program ends

• The program pauses

• The program restarts and Millis returns 0

• The program continues from where it stopped

What is the purpose of using a delay in an Arduino program?

• To stop the program

• To slow down the execution

• To create a pause between actions

• To speed up the execution

What is the difference between Millis and Micros functions?

• Millis gives time in seconds, Micros in milliseconds

• Millis gives time in milliseconds, Micros in microseconds

• Millis gives time in microseconds, Micros in milliseconds

• Millis gives time in hours, Micros in minutes

Which function would you use for more precise time measurement than Millis?

• Delay

• Millis

• Micros

• Serial
