If a single else branch is not enough to manage the logic of our Arduino project, we can insert as many if.else if branches we want. The if () statement is the most basic of all programming control structures.
ARDUINO ELSE IF COMMAND CODE
Try changing the value of my variable and trying to figure out which block of code will be executed. If you wish to help us continue developing and maintaining this project, you can always make a donation Hardware Childs Play Scratch for Arduino (S4A) is a. Serial.println ("myVariable is not greater than 5") In questo caso il codice assumerà l’aspetto seguente: if (myVariable> 5) Possiamo quindi aggiungere al test condizionale un ramo else.
Spesso un test condizionale non è sufficiente potremmo ad esempio voler eseguire del codice se miaVariabile non è maggiore di 5. What happens if we assign the value 4 to myVariable? If.else statement Serial.println ("myVariable is greater than 5") Kit di apprendimento completo per i principianti int myVariable = 7 The rules for writing the body of instructions within if apply to all other instructions in an Arduino sketch, including the body of functions (which we will explore in a future article).įor example, if we wanted to verify that the value of a certain variable is greater than 5, we would have to write the following code: The Arduino IDE automatically inserts the indent of the code and the closing parenthesis as soon as you type the opening brace (another good reason to always use them!). There is a common variation called if-else that looks like this: Copy. In reality, if the instruction to be executed is unique, it is possible to omit them, however for greater clarity it is a good idea to always insert the brackets and add indents to the code written inside them (in this case I used four spaces, but you can use for convenience also the tabulation character). The if else allows greater control over the flow of code than the basic if statement, by allowing multiple tests to be grouped. Use an if statement to change the output conditions based on changing the input conditions. The block of statements that must be executed if the if test is true is enclosed in curly brackets. code to execute if the condition is true
The if statement, also called conditional test, is designed to check if a certain condition occurs.
