Arduino for Beginners - 2022 Complete Course - The Problem with delay ()

The video tutorial discusses the limitations of using the delay function in Arduino programming. It explains how delay can block program execution, causing timing issues when trying to perform multiple tasks, such as blinking LEDs at different rates or reading sensor data. The tutorial provides examples of these challenges and introduces the concept of multithreading as a solution, highlighting the need for alternative time functionalities to manage multiple actions effectively.

What is the primary function of the delay command in programming?

• To speed up the execution of a program

• To pause the execution of a program for a set time

• To execute multiple tasks simultaneously

• To enhance the program's security

Why is using delay problematic when trying to perform multiple tasks?

• It allows tasks to run in parallel

• It can cause tasks to execute too quickly

• It prevents tasks from being executed simultaneously

• It enhances the program's efficiency

What issue arises when trying to blink two LEDs at different rates using delay?

• The program will become too complex

• One LED may miss its blink timing

• The program will crash

• The LEDs will blink at the same rate

How does delay affect reading sensor data while another task is running?

• It improves data accuracy

• It causes a delay in data reading

• It allows immediate data reading

• It has no effect on data reading

What is a potential solution to the limitations of using delay in Arduino programming?

• Using faster processors

• Increasing the delay time

• Implementing multithreading

• Using other time functionalities
