Variables Variables give a name to a number. Actually, they can be a lot more powerful than this, but for now, we’ll use them for this purpose. When defining a…

A variable of type int in Arduino C uses 2 bytes of data. Unless a sketch becomes very memory hungry, then ints tend to be used for almost everything, even…

Because Arduino boards have a quite limited amount of memory, you’ll find it worthwhile to only include code that will actually be used in what ends up on the board.…

Now that you have an understanding of where all the magic code comes from when you write a simple Arduino sketch, let’s look at exactly how that code gets into…

The Wiring framework gives Arduino its easy-to-use functions for controlling the hardware pins; however, the main structural part of the language is all provided by C. In early versions of…

The Arduino family of boards mostly use microcontrollers made by the company Microchip. They all have similar hardware design principles and, with the exception of the microcontrollers used in the…

It may be that your Arduino was already blinking when you first plugged it in. That is because the Arduino is often shipped with the Blink sketch installed. If this…

The Arduino Uno is the current incarnation of the original Arduino board. It is the most common Arduino board and is generally what people mean when they say they are…

What Is Arduino? The term Arduino is used to describe both the physical Arduino board (of which the most popular type is the Arduino Uno) and the Arduino system as…

The software that you use to program the Arduino is called the Arduino Integrated Development Environment (IDE). If you are a software developer and accustomed to using complex IDEs like…
