Chapter 1

An Introduction to Arduino

With the technological advancements of the modern age, people are increasingly exposed to some form of hardware or software on a daily basis. Whether it be professionals, hobbyists, or even ordinary people, this exposure has led to a technological literacy higher than ever before.

A higher literacy naturally means people are more aware and take a keen interest in the technologies surrounding them. Arduino programming is one target of such an interest that has led to its exponential growth. Since its inception in 2005, Arduino has progressed in leaps and bounds and traversed the borders of its home country, Italy, to the rest of the globe.

Whether you're attracted to Arduino for its flexibility, or you've seen projects that result from Arduino technologies, your attraction to the technology is the result of such an interest. Whatever it may be, before you get around to utilizing Arduino efficiently, you should familiarize yourself with its history and the concept of its existence.

What Is Arduino?

A solid definition of Arduino might be challenging to grasp for some beginners; this is because the explanation is often riddled with technicalities such as open-source, environments, and IDEs.

All technicalities aside, the simplest definition of Arduino, provided by its official platform, states that Arduino is simply an open-source platform/community with hardware and software that is easy to use and understand.

Being an open-source platform, Arduino can be taught and redistributed without violating any sort of copyright laws. In other words, the founders/creators of Arduino have allowed everyone to experiment with their hardware and software legally by not owning the rights to any of the ideas behind the foundation of the platform.

With its easy-to-understand nature, Arduino software and hardware can be understood and manipulated even by regular people with little research. The Arduino community mainly centers around creating packages for use in robots and other electronic gadgets.

The hardware used by the Arduino community is termed microcontrollers. These are essentially micro-computers intended for small tasks, unlike conventional computers such as laptops, tablets, or desktop PCs.

How Does Arduino work?

People who work with Arduino usually have a specific product in mind. According to their goals, they purchase appropriate hardware and upload codes into it using a powerful operating system such as Linux, Windows, or Macintosh OSX.

These codes are uploaded into the device using a cable and are essentially a set of instructions mapped out for the microcontroller to perform; this can vary from producing a beeping sound when exposed to light to making a random turn after sensing a presence ahead according to the type of microcontroller chosen.

Why Do People Use Arduino?

Arduino is quite a popular and approved platform mainly due to its flexibility and availability. Overall, it has quite an uncomplicated user experience, making it easy to use while retaining enough versatility to appeal to more advanced developers and engineers. While Arduino isn't the only microcontrollers platform out there, it does offer a few advantages which contribute to its popularity over the others:

Arduino microcontrollers are relatively inexpensive.

In fact, a significant reason behind the inception of Arduino was to create an inexpensive and straightforward programmable device that could be used for projects in interactive art design by novices and professionals alike. Consequently, Arduino boards are pretty cheap compared to the microcontrollers offered by some other platforms. While the most affordable Arduino board can be brought unassembled, even the assembled versions don't go above $50 in cost.

Arduino is an open-source platform.

The benefits of an open-source platform go without saying. It provides opportunities for newbies to gain experience by tweaking around with official software without worrying about legal issues. In contrast, seasoned veterans can use the overhaul of the existing software and hardware to come up with and publish their version of the Arduino platform.

Arduino is cross-platform

The Arduino IDE works across platforms. In other words, it can work in Windows, Linux, and Macintosh OSX, a quality not many microcontroller boards have. Hence, Arduino software and hardware are as easily accessible to Apple and Linux (which itself is open-source) users as it is to Windows users.

What Type of People Use Arduino?

Arduino is used by a vast range of people, which can be attributed to its inexpensive and cross-platform properties. People use it for hands-on professional development and hobby projects alike. While the Arduino programming language is widely considered easy to understand, it is still rich and complex enough for a beginner to grow and mature his career. Furthermore, it also has enough flexibility and potential to catch the eyes of the most advanced users.

With all of these properties, Arduino users do not fall into specific categories. However, some examples of people who use Arduino include:

Teachers and students alike. They were, after all, the original consumer base intended for the product. Educators primarily use Arduino to construct low-cost experiments designed to highlight physics or chemistry principles or to get started with building robots or coding in general.

Architects and designers can build inexpensive and interactive prototypes or models of their work to use as a reference for their full-scale projects.

Almost anyone can use Arduino, and this is precisely the case. Amongst the Arduino community, you'll find people of all ages and professions to share concepts with and improve your understanding of the platform further.

What Are Some Arduino Terminologies to Get Used To?

If you're looking to improve your manipulation of the Arduino programming language as a beginner, you'll have to ensure you're familiar with all the core Arduino terminologies and their uses.

Arduino's In-Board Terminologies

Up to this point, you've familiarized yourself with the platform’s core concepts, such as its open-source nature and the implementation of microcontrollers as hardware. However, that isn't all. While the term microcontrollers can be used interchangeably with Arduino hardware, microcontrollers aren't all the Arduino boards have to offer.

Most microcontrollers have digital pins which run along the edges of the board. These "digital pins" are used for input and output tasks. The input is what prompts the board to emit a response known as the output. For example, in a simple nightlight project, the input would be the lack of light in the room; without sufficient light, the light sensor would send a signal to the microcontroller, which would prompt it to close the circuit and activate the nightlight, the output.

There are also "Analog in" pins, which are quite often located opposite the digital pins. These pins register a varying input, for example, quantities such as temperature and pressure, which can fluctuate with time.

The board also has 5V and GND pins which can connect an extra 5V power to the board; the board also has a USB connector, which is mainly used to upload your instructions but can alternatively be used as a power source too. The USB connector is the main port used to connect the cable between the board and the device your code is on.

Aside from that, there are the power and pin LEDs. As the name states, the power LED signals whether the board is receiving power or not; the LED lights up when it does, making debugging easier. The pin LED is often a specific pin on the board and is used for debugging.

Other LEDs, such as the RX and TX LEDs, light up whenever information transfer occurs; this is usually when you transfer your code from the primary device to the controller. Your code or instructions are commonly referred to as sketches, and these pins blink rapidly whenever such a transfer occurs.

Finally, there's the microcontroller itself. The microcontroller exists on every Arduino board, and you can think of it as the brain; it receives your sketch and acts according to the instructions you've written. It'd be safe to say that without the microcontroller, there'd be no way for any function across the board to take place.
