The interest in state machines started in the 1950s when George Moore and Edward Mealy published seminal papers on formal methods of designing digital circuits, which generate outputs based on the ...

Making time for my next small Arduino project, I need to do something with the rotary encoder direction information decoded by this software. A state machine is what I need, but how to implement it?

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 ...
