Summary
In this first chapter we have learned all the basic information about an Arduino, especially Arduino Uno. Don't worry about other types of Arduino, because they have almost the same functionalities. Sometimes the number of pins is greater, or the microcontroller is faster (and so on) on other types of Arduino.
I would suggest you read the whole chapter and get to know your Arduino better for the following chapters. If you want to learn only C programming, not for Arduino, then you can skip this chapter.
