## What is a state machine in Arduino?

A state machine is implemented by defining state logic as a function in your sketch. Transitions are implemented as functions returning a boolean value and a next state number.

## What is a state machine microcontroller?

A state machine (more formally, a finite state machine), as used in this article, is a mathematical structure in which the next state is determined only by the previous state and by the inputs to the machine.

What is the best reason why we would use finite state machines in Arduino programming?

In other words, a FSM can be the right choice on many occasions with our development board for a number of very good reasons:

• Finite state machines are flexible.
• Easy to move from a significant abstract to a code execution.
• Easy determination of reachability of a state.

### What is a state machine in computer science?

State machines are an abstract way of thinking about how computers and computations work. They are especially useful for describing reactive systems such as user interfaces that need to respond to events from the outside. A state machine has some internal state that can be changed in response to an external event.

### What is an example of a state machine?

There are many more examples of finite state machines we could use: a vending machine. a subway entrance turnstile. a heating system.

What is state machine in software engineering?

A state machine is any device storing the status of something at a given time. The status changes based on inputs, providing the resulting output for the implemented changes. A finite state machine has finite internal memory.

#### What is a state machine diagram What are the main elements of a state machine diagram?

State diagrams mainly depict states and transitions. States are represented with rectangles with rounded corners that are labeled with the name of the state. Transitions are marked with arrows that flow from one state to another, showing how the states change.

#### What is the purpose of a state machine diagram?

State machine diagram typically are used to describe state-dependent behavior for an object. An object responds differently to the same event depending on what state it is in.

What is state state machine?

A state machine reads a set of inputs and changes to a different state based on those inputs. A state is a description of the status of a system waiting to execute a transition. A transition is a set of actions to execute when a condition is fulfilled or an event received.
