Part $4$: Compare Delays and Interrupts

$1.$ Task:

$-$ Compare and contrast the use of delay $()\backslash (,\backslash$operatorname$\{$millis$\}()\backslash ),$ and interrupts for time management and handling external events.

$-$ Discuss when each method is most appropriate and efficient.

$2.$ Questions for Discussion:

$-$ In what types of applications would delay$()$ be acceptable or even preferable?

$-$ When are interrupts absolutely necessary?

$-$ Can interrupts be overused or misused? If so$,$ how?

Extension Activity:

$-$ Add a second button that controls a different LED using interrupts, while the first button continues to toggle the original LED using millis $().$ This helps students explore how multiple interrupts and non$-$blocking delays can work together.

Assessment Criteria:

$-$ Correct implementation of delay $(),$ millis $(),$ and interrupts.

$-$ Clear understanding of when to use each method.

$-$ Correct handling of time$-$sensitive tasks and event$-$driven programming.
