This installment starts a new segment of lessons about state machines. The subject conceptually continues the event-driven theme and is one of my favorites [1,2]. Today, you’ll learn what event-driven ...

As opposed to conditional flag-centric code, a state machine diagram presents a very clear view of the design, and so provides a good example to students. As opposed to conditional flag-centric code, ...
