Many people who are new to Arduino often find it tricky to understand the difference between analog and digital pins on the Arduino board. They get confused about where and how to connect electronic components and sensors to the board, wondering whether to connect them as outputs or inputs. Choosing the code functions usually makes it a little bit difficult for beginners.
In this article, we’ll simplify all these challenges to make them as straightforward as they should be. We’ll discuss the distinctions between analog and digital signals, as well as the variations between reading from inputs and writing to outputs. We’ll also cover how to implement these concepts in your code. It’s important to note that our focus will be on the Arduino Uno type, bearing in mind that different types of Arduino boards may have varying numbers of digital or analog pins.
