Another Interrupt Example: Arduino Course 9.4

In this lesson, the instructor reviews the previous session's project involving an LED and button. The focus is on using flags in interrupt service routines (ISRs) to manage tasks that are not time-sensitive. The lesson also covers implementing a counter variable within an ISR to count button presses. The instructor explains the importance of using volatile qualifiers for variables in ISRs and demonstrates how to print messages to the serial monitor based on events. The session concludes with a review of the concepts and encourages students to engage with challenges.
