That is why the default statement is executed. Serial.println("One of the cases is true") Īs we can see in the output above, none of the cases in the above code is true. The || symbol, also known as the OR operator, is used when we want to execute a task even when one condition is true from all the given conditions.įor example, let’s define two conditions to check the range of a number and print a specific text. The & symbol, also known as the AND operator, is used only if all the given conditions are true when we execute a task. When using if.

#Arduino else if how to
This tutorial shows you how to use it to switch between four desired states of a photo resistor: really dark, dim, medium, and bright. Switch allows you to choose between several discrete options. If we want to check multiple conditions before doing a task, we can also use the & and || operators. Arduino - Ifelse if else statement Advertisements Previous Page Next Page The if statement can be followed by an optional else if.else statement, which is very useful to test various conditions using single if.else if statement. When there are more than two options, you can use multiple if statements, or you can use the switch statement. We used the delay() function to add some delay in the code. The output shows that the text World is printed on the serial monitor, which means the first condition is true and the second is false. We can also add an if statement inside the second if statement in the above code.įor example, let’s create a nested if statement, check the given number, and print a text according to the conditions. In the above code, if the first condition is true, the program will check the second condition, and if it is also true, the code inside the second condition will be executed. We can define the second if statement inside the scope of the first if statement. If we want to check one and it is true, we want to check another condition,

The if statement in Arduino defines conditions like doing a task if certain conditions are fulfilled. This tutorial will discuss adding an if statement inside another using the nested if statement in Arduino.
