Introduction to Interrupts: Arduino Course 9.1

The video tutorial introduces basic programming design, focusing on polling and its sufficiency. It uses a locomotive story to illustrate the need for prioritizing tasks in code execution. The tutorial then explores methods to improve code by using interrupts to prioritize tasks, ensuring critical functions are executed promptly.

What has been the main programming design philosophy in the course so far?

• Random and unordered

• Simple and step-by-step

• Complex and detailed

• Fast and efficient

What is the main advantage of using polling in programming?

• It is fast and efficient

• It is random and unordered

• It is easy and sufficient for current needs

• It is complex and detailed

In the train system example, what is the main issue with the current code structure?

• It is too fast

• It lacks a priority system

• It is too simple

• It is too complex

What is the worst-case scenario for the train stopping time in the current polling system?

• 30 seconds

• 35 seconds

• 40 seconds

• 45 seconds

What is one proposed solution to improve the priority of the stop train function?

• Ignore it

• Remove it from the loop

• Move it to the bottom of the loop

• Move it to the top of the loop

How can the stop train function be prioritized without rearranging the loop?

• By using interrupts

• By ignoring other functions

• By making it the only function

• By slowing down other functions

What is the main benefit of using interrupts in programming?

• They make programming more complex

• They allow for prioritization of tasks

• They slow down the program

• They simplify the code

What is a potential downside of using interrupts?

• They make the program too fast

• They slow down the program

• They simplify the code too much

• They make programming life more complicated

What hardware feature does the Arduino use to implement interrupts?

• An external device

• A special software library

• The ATmega328 microcontroller

• A unique programming language

What is the main topic of the next lessons after this one?

• Advanced polling techniques

• External and internal interrupts

• Basic programming design

• Simple task execution
