Arduino is an open-source electronic prototyping platform. Because it is open-source, there are many tutorials and documentation using it across the internet.
For this course we will be using the Arduino Uno board, which is a popular choice for beginners. There are many “flavors” of Arduino that you can choose from depending on what you want to build.
Documentation is important when it comes to engineering. I recommend checking out the Arduino website, the Arduino Uno Store page, and the Getting Started page. Read through these sites carefully because there will be a quiz on this information in the next section.
