A switch statement allows a variable to be tested for equality against a list of values. If we use typedef directly when declaring the enum, we can omit the tag name and then use the type without the enum keyword: typedef enum { RED, GREEN, BLUE } color; color chosenColor = RED; But in this latter case we cannot use it as enum color, because we didn't use the tag name in the definition. In this example this occurs cyclically in an endless loop. A switch case allows you to use a variable or value and create a series of outcomes or cases depending on the value results. I guess in theory it should be possible to use some sort of hashing function to generate integral values from strings which could then be used in a switch .

Now that we know the basics of a switch statement, we can add in a basic digital input. A finite state machine (FSM) is a theoretical machine that only has one action or state at a time. In particular, a switch statement compares the value of a variable to the values specified in case statements. switch (Counter) { case 1: Serial.print("The counter reached number 1"); Counter++; break; The next two cases that we will encounter are if the variable Counter reaches the number 10 or 15. En particular, una sentencia switch compara el valor de una variable con los valores especificados en las instrucciones case. About. Other data types such as strings will need if statements to match cases. Switch (case) Statement, used with serial input - Arduino An c# enum type variable can take one of the values listed in the Enum (here the enumeration CivilState which includes four values): enum CivilState {Single, Married, Divorced, Widower} ... CivilState; // cs is a CivilState variable cs = CivilState. Arduino Alarm System - Arduino Project Hub enum LED_References_e { ALL = 0, LED1 = 1, LED2 = 2, LED3 = 3, LED4 = 4 }; When using the enumerated values as cases to the statement, the statement always hits the default clause. But now you have a class, and can add own conversion methods and operators to handle your special cases. Output strings from the Arduino to Laptop.
