Unraveling Arduino Functions: A Guide to Understanding and Implementing Functions in Arduino

Learning Objective

Understand the concept of Arduino functions, common functions, function return type, function name, and function parameters.

What do you already know about Arduino Functions?

Introduction to Arduino Functions

Arduino functions are blocks of code that carry out specific tasks. They provide a way to modularize code and make it reusable.

Common Functions in Arduino

Common functions in Arduino include pinMode(), digitalWrite(), analogRead(), and delay(). Each serves a specific purpose in controlling hardware and performing tasks.

How Functions Work

Functions are called by their name and can take input parameters. When called, they execute the code inside them and can return a value if specified.

Function Return Type

The return type of a function defines the type of value the function will return, such as int, float, void, or other data types.

Function Name

The function name is the identifier used to call the function. It should be unique and descriptive of the function's purpose.

Function Parameter

Function parameters are the input values that a function can accept. They allow the function to receive data and perform operations based on that data.

Practical Application

Students will apply their understanding by writing and implementing functions in Arduino code to control a specific task.

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.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
