Arduino: The Easiest Way to Build an Internet of Things Product

Arduino is an open-source electronics platform based on easy-to-use hardware and software. This platform has created excitement in the maker community because it allows people with almost no prior programming experience or technical knowledge to build interactive physical environments quickly. The Arduino system consists of two parts: a microcontroller board with all the circuitry you need to power your project; and a development environment that runs on your computer, which talks to the board via USB or a wireless connection. Arduino boards are available from many suppliers worldwide. This article will discuss what this platform is and how it works, providing some essential tips about Arduino projects like interfacing different devices into one application, using sensors for input, adding actuators for output, and using arrays to store information.

What Exactly is Arduino?

Arduino is an electronics platform based on open-source hardware and software. Because they are open-source, Arduino boards are available from many suppliers worldwide, with the most common being Arduino LLC in Italy.

It is a platform for controlling electronic devices by a computer program, usually written in the programming language of C++. The system consists of two parts: a microcontroller board with all circuitries you need for your project; and a programming environment that runs on your computer to talk to the board.

Arduino boards come in various shapes and sizes, from the most popular one called Uno with just 14 digital input/output pins to the Leonardo, which has 20 digital input/outputs and twice more analog pins. Uno has become the industry standard for developing boards.  Arduino projects range from small interactive physical environments with a few inputs and outputs (such as an alarm clock that wakes you up in the morning) to large interactive environments with many inputs and outputs (such as a robotic lawnmower).

The History of Arduino

Before Arduino came around, if you wanted to create a physical device with an onboard computer, you needed extensive knowledge of electrical engineering, programming, and hardware.

The Arduino project, however, started with the idea of simplifying things for people who weren’t trained engineers. The founder’s vision was to create a chip but without all the complexities of a chip. They made a microcontroller with its built-in program and data memory, and that is how Arduino was born. In contrast to a PC processor where any external circuitry would be required, the Arduino board is fully self-contained.

The initial code for Arduino started in 2003 as a school assignment at Interaction Design Institute Ivrea (IDII) in Italy. That year, IDII alumni Hernando Barragán created the development platform ‘Wiring’ as a Master’s thesis project.

Two years later, Massimo Banzi and David Cuartielles used Barragán’s work to provide a user-friendly sensor board. David Mellis developed the Arduino programming language, which was based on Wiring. The five original founders of Arduino are known as Gianluca Martino, Tom Igoe, David Cuartielles, Massimo Banzi and David Mellis.

Benefits to Using the Arduino Platform

There are numerous benefits to using an Arduino platform for your next project, including:

  • Easy And Affordable to Buy: You can simply go to Amazon.com or another online retailer to buy an Arduino board for nearly $12.
  • Interact With Electronics Components: For example, if you want to control a light bulb, the Arduino will take care of powering it on and off as well as turning its brightness up or down. You can even set timers to make sure your lights are always running at optimal levels.
  • Use Sensors for Input: Sensors are one of the essential tools for Arduino projects. They can measure, compute and interact with the physical world in ways that change how you work.
  • Add Actuators for Output: Actuators are what make your lives easier by executing an action whenever they receive a signal from your program, such as opening or closing a door lock when someone rings the doorbell.
  • Accessible: You can create electronics projects without knowing how to design circuits or be a professional coder. You need a basic knowledge of C++. You will mainly copy and paste code from the internet.
  • Versatile: The platform’s open-source nature means that there are many different variations on the hardware you can use, for example, thinner boards or more advanced sensors.
  • Sustainable: Arduino boards are designed in a way that can be easily replaced if they break.
  • Solderless: The Arduino is not a traditional circuit board because you don’t need to solder any connections. You simply wire the electronic components together on the Arduino, and it should work out of the box.

How To Get Started with Your First Project on An Arduino Board?

Everyone’s first project may be different, but there are a few basic things to consider. First, what do you want your Arduino board and the accompanying program to do? What objects or components will it need to interact with – such as sensors for inputs or actuators for outputs?

Next, think about how these objects and their functions will connect to the board, such as connecting a light sensor to an analog input or attaching servo motors to digital outputs. The pins on Arduino boards are numbered, and you will need this information when programming your project.

There are also plenty of resources available on how to start programming with Arduino boards, including tutorials from both beginner and advanced levels that can help you understand the basics of C++ to more complicated topics like creating your own printed circuit boards (PCB). There are also countless blogs, books, tutorials, videos, and other online resources for making your first Arduino project from start to finish.

For instance, Arduino provides example projects for many typical applications in its online documentation section. Here on Arduino’s Project Hub, you can find numerous projects with their source code. They include, for example, a smart coffee machine that works via Bluetooth and a device that tells the ripeness of fruits by their color.

In brief, the Arduino platform is a versatile and easy-to-use electronics system that provides many benefits for your next project. Best of all, there is a massive online community that can help you get started with projects and provide tutorials to learn how to build your own Arduino boards. Why not get on board the Internet of Things (IoT) revolution and turn your creativity into practice?
