Introduction to Interrupts Continued: Arduino Course 9.2

The video tutorial introduces the concept of interrupts in microcontrollers, focusing on the Arduino platform. It explains how interrupts can prioritize tasks by stopping the main code loop to execute specific functions, known as interrupt service routines (ISRs). The tutorial covers two main types of interrupts: external, triggered by voltage changes at pins, and internal, often based on timers. Practical examples, such as using buttons or integrated circuits, illustrate how interrupts can be used to handle new data efficiently. The video concludes with a review of the key concepts and encourages viewers to engage with the material through challenges.

Describe how a button can be used to trigger an interrupt.

What is an interrupt service routine (ISR) and how is it related to interrupts?

In what scenarios might using interrupts be more beneficial than polling?
