Section 3.1 - Introduction to the Arduino
So what exactly is an Arduino?
In this lesson, you’ll be introduced to the basics of Arduino, focusing on the microprocessor itself and its key components. Through slides, you’ll get an overview of the different types of pins on the Arduino, such as digital and analog pins, and the USB port used for uploading code. You’ll also learn to think of the pins as tiny ports that allow you to connect various components, similar to ports on a computer. This analogy helps you understand Arduino’s role as a “mini-computer” in electronic projects. In TinkerCAD, you’ll then see the Arduino in action, starting a simulation that effectively “plugs” in the USB port, both powering the Arduino and loading your code. This hands-on demonstration introduces you to the fundamental workings of Arduino and prepares you to start coding and connecting components in future projects.
