Exploring Arduino: Conditional Statements and Loops

Learning Objective

At the end of the lesson, you will be able to understand the concepts of if-else statements, else-if statements, the Arduino loop, and the Arduino while loop.

What do you already know about Arduino conditional statements and loops?

What is Arduino if-else?

Arduino if-else is a conditional statement that allows the program to execute different codes based on whether a specified condition is true or false.

What is Arduino else-if?

Arduino else-if is a conditional statement that provides an alternative condition to be tested if the initial condition in the if statement is false.

Practical exercise #01 

Arduino's if, else if, and else statements to control an LED based on different conditions. In this example, we'll use a simulated scenario where the Arduino reads an analog input (like a potentiometer) and adjusts the brightness of an LED accordingly.

Understanding Arduino Loop

Arduino loop is a function that runs continuously in a program, allowing the execution of code repeatedly without the need for manual intervention.

How to Use Arduino Loop

In Arduino, the loop function is where the main program logic is placed, and it is executed repeatedly as long as the Arduino board is powered on.

Exploring Arduino While Loop

Arduino while loop is a control flow statement that repeatedly executes a block of code as long as a specified condition is true.

Benefits of Arduino While Loop

The while loop is useful for scenarios where a specific action needs to be repeated until a certain condition is met, providing a flexible and efficient way to control program flow.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
