Arduino for Beginners - 2022 Complete Course - What Are Interrupts and When to Use Them

The video tutorial explains the concept of interrupts using a real-life example of package delivery. It contrasts interrupts with polling, highlighting the efficiency of interrupts in responding to changes in button states. The tutorial covers different interrupt modes: rising, falling, change, and low, and discusses their applications. It also provides information on which digital pins can be used for interrupts on various Arduino models, emphasizing the advantages of using interrupts for efficient program execution.

How does the timing of actions change when using interrupts instead of polling?

What types of digital pins can be used for interrupts on different Arduino models?

Why might a user miss a state change when using polling?
