Most embedded systems are reactive by nature. They measure certain properties of their environment with sensors and react on changes. For example, they display something, move a motor, or send a ...

State machines and related modeling techniques are commonly used in the production of safety-critical software (like in the aerospace and defense industries, nuclear power plants, transit systems, ...

Imagine a robot with an all-around bump sensor. The response to the bump sensor activating depends on the previous state of the robot. If it had been going forward, a bump will send it backwards and ...

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 ...

State machines are so common that there are tools devoted to creating them by drawing circles and arts. There are simulators that will recognize your state machine ...
