Introduction to Arduino: The Basics of Coding and Hardware

Slide 1 - Slide

This item has no instructions

Learning objective
At the end of the lesson, you will have a basic understanding of Arduino hardware and coding, and be able to create simple programs.

Slide 2 - Slide

Explain the learning objective clearly to the students before proceeding with the lesson.
What do you already know about Arduino and coding?

Slide 3 - Mind map

This item has no instructions

What is Arduino?
Arduino is an open-source electronics platform based on easy-to-use hardware and software.

Slide 4 - Slide

Explain that Arduino is a popular platform for creating interactive projects and that it is widely used in the maker community.
Arduino Hardware
Arduino boards come in various shapes and sizes, but they all have the same basic components: power supply, microcontroller, digital and analog pins, and USB port.

Slide 5 - Slide

Show examples of different types of Arduino boards and their components.
The Microcontroller
The microcontroller is the brain of the Arduino board. It is responsible for executing the code and controlling the input/output pins.

Slide 6 - Slide

Explain the role of the microcontroller and how it interacts with the other components of the Arduino board.
Digital Pins
Digital pins can be used for both input and output. They can be turned on or off using digital signals (0 or 1).

Slide 7 - Slide

Show examples of digital input/output projects that can be created using Arduino.
Analog Pins
Analog pins can be used for reading analog signals (0-1023) from sensors or for outputting analog signals using pulse-width modulation (PWM).

Slide 8 - Slide

Explain the difference between digital and analog signals and show examples of analog input/output projects that can be created using Arduino.
The USB Port
The USB port is used for uploading code to the Arduino board and for serial communication with a computer.

Slide 9 - Slide

Demonstrate how to connect the Arduino board to a computer and how to upload code to the board.
What is Coding?
Coding is the process of creating instructions for a computer to follow.

Slide 10 - Slide

Explain that coding is used to create programs that can be executed on the Arduino board.
The Arduino IDE
The Arduino Integrated Development Environment (IDE) is a software application that is used to write and upload code to the Arduino board.

Slide 11 - Slide

Demonstrate how to download and install the Arduino IDE and how to create a new project.
The Setup Function
The setup function is a special function that is called once when the Arduino board is powered on or reset. It is used for initializing variables and setting up the board.

Slide 12 - Slide

Explain the purpose of the setup function and show examples of how it can be used to set up the board.
The Loop Function
The loop function is a special function that is called repeatedly after the setup function has been called. It is used for executing the main program.

Slide 13 - Slide

Explain the purpose of the loop function and show examples of how it can be used to create simple programs.
Variables
Variables are used to store values that can be used later in the program. They can be of different data types, such as integer, float, or boolean.

Slide 14 - Slide

Explain the concept of variables and show examples of how they can be used in programs.
Conditional Statements
Conditional statements are used to execute different code depending on whether a certain condition is true or false. They include if, else if, and else statements.

Slide 15 - Slide

Explain the concept of conditional statements and show examples of how they can be used in programs.
Loops
Loops are used to repeat a section of code multiple times. They include for and while loops.

Slide 16 - Slide

Explain the concept of loops and show examples of how they can be used in programs.
Functions
Functions are used to break up a program into smaller, reusable parts. They can be called multiple times throughout the program.

Slide 17 - Slide

Explain the concept of functions and show examples of how they can be used in programs.
Interacting with Hardware
Interacting with hardware involves reading input from sensors and controlling output to actuators. This can be done using digital and analog pins on the Arduino board.

Slide 18 - Slide

Show examples of projects that involve interacting with hardware, such as controlling an LED or reading data from a sensor.
Serial Communication
Serial communication is a way for the Arduino board to communicate with a computer or other devices. It involves sending and receiving data one byte at a time.

Slide 19 - Slide

Demonstrate how to use serial communication to send and receive data between the Arduino board and a computer.
Debugging
Debugging is the process of finding and fixing errors in code. It involves using tools such as the serial monitor and debuggers.

Slide 20 - Slide

Explain the importance of debugging and show examples of how to use debugging tools to find and fix errors in code.
Wrapping Up
In this lesson, we covered the basics of Arduino hardware and coding. You should now have a basic understanding of how to create simple programs and interact with hardware using the Arduino board.

Slide 21 - Slide

Review the key concepts covered in the lesson and ask if there are any questions before moving on to the next lesson in the series.
Write down 3 things you learned in this lesson.

Slide 22 - Open question

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.

Slide 23 - Open question

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.

Slide 24 - Open question

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.
