A recent Facebook comment caught my attention:

"Who's using Arduino IDE in 2026?"

At first, I dismissed it as another attempt to provoke a reaction. But the more I thought about it, the more I realized that it reflects a common misconception. Many engineers still associate the Arduino IDE exclusively with hobbyists building blinking LEDs and garage projects.

Nothing could be further from the truth.

The Arduino IDE has quietly become one of the most influential embedded development environments available today. While professional developers certainly have alternatives—and some projects demand them—the Arduino ecosystem has grown into an engineering platform that reaches an enormous community and supports an impressive range of professional hardware.

It Was Never About the Board

One of the biggest misunderstandings is assuming that Arduino equals Arduino hardware.

In reality, the Arduino IDE has become a universal development environment.

Today you can target platforms such as:

• Arduino AVR boards

• Arduino ARM-based boards

• ESP32

• Teensy

• STM32

• Raspberry Pi Pico

• ARM Cortex-M microcontrollers

• Numerous third-party CAN, Ethernet, Wi-Fi, and industrial controllers

For many embedded projects, changing hardware platforms is often little more than selecting another board definition and adapting the hardware-specific interface layer.

That portability is incredibly valuable.

A Massive Ecosystem

No embedded development environment can match the amount of publicly available code written for the Arduino ecosystem.

Need a CAN driver?

There are several.

Ethernet?

Multiple choices.

Modbus?

MQTT?

USB?

GPS?

SD cards?

Industrial sensors?

Someone has probably already solved part of your problem.

This doesn't mean blindly copying code from the Internet. Professional engineers still evaluate, optimize, and validate everything they use.

But having thousands of proven examples dramatically shortens development time.

Why reinvent a UART driver when thousands already exist?

The Fastest Path from Idea to Prototype

Every engineering project begins with one question:

Does the concept actually work?

The Arduino IDE answers that question faster than almost any other environment.

Within minutes you can:

• install the IDE

• select a board

• install the required libraries

• compile

• upload

• start testing

There is virtually no learning curve compared to many vendor-specific IDEs that require extensive project configuration before writing the first line of code.

Rapid prototyping is not a luxury.

It is often the difference between completing a project in weeks instead of months.

Professional Products Are Built This Way

There is another misconception worth addressing.

Many assume that serious commercial products cannot possibly be developed with the Arduino IDE.

Our own products prove otherwise.

The Copperhill JCOM1939 gateway family has been developed using the Arduino IDE while targeting multiple processor platforms. The firmware architecture deliberately separates hardware-specific code from application logic, making it straightforward to migrate the software between different microcontrollers.

The same application architecture can be adapted to:

• Arduino platforms

• ESP32

• Teensy

• STM32

• ARM Cortex devices

• and additional hardware with relatively minor effort

The development environment is simply a tool.

Customers care about reliability, functionality, and maintainability—not which IDE was used to build the firmware.

Reaching the Largest Community

From an educational standpoint, supporting the Arduino IDE is an easy decision.

If I publish example code in a vendor-specific IDE, I immediately limit the audience to owners of that particular hardware.

If I publish Arduino-compatible code, engineers can often run it on completely different hardware by making only small adjustments.

That dramatically increases the usefulness of tutorials, books, and open-source projects.

For my upcoming book J1939 Development for Embedded Systems, this is a key consideration.

I want readers to focus on learning SAE J1939—not on spending days configuring a proprietary development environment before compiling their first example.

Every Tool Has Its Place

None of this means the Arduino IDE is perfect.

Professional environments such as STM32CubeIDE, Microchip Studio, MPLAB X, Keil MDK, IAR Embedded Workbench, Segger Embedded Studio, or Visual Studio Code with PlatformIO offer capabilities that are indispensable for certain projects.

When developing extremely complex applications, working with RTOS-aware debugging, advanced performance analysis, or manufacturer-specific peripherals, these environments can provide significant advantages.

The Arduino IDE should not be viewed as a replacement for every professional tool.

It should be viewed as one of the best front ends for rapid embedded development.

What About Debugging?

One criticism often raised is debugging.

That criticism was completely justified years ago.

The classic Arduino IDE relied heavily on Serial.print() debugging because it had no integrated debugger.

However, that is no longer entirely true.

Arduino IDE 2 includes integrated debugging with breakpoints, single-step execution, variable inspection, and call stack support—but only on boards that provide the necessary hardware debugging capabilities. Many newer ARM-based boards support this directly or through an external debug probe, while classic AVR boards such as the Uno and Mega still generally rely on traditional techniques like serial output unless additional debugging solutions are used.

So, debugging support is no longer a limitation of the IDE itself; it depends largely on the capabilities of the target hardware.

The Bottom Line

The Arduino IDE has long since outgrown its origins.

It has become one of the most accessible, portable, and productive embedded development environments available today.

It enables rapid prototyping.

It supports an enormous variety of hardware.

It gives developers access to one of the largest embedded software ecosystems ever assembled.

And yes—it powers commercial products used in the field every day.

Could another IDE offer more specialized features?

Absolutely.

Should every embedded engineer know other development environments?

Certainly.

But dismissing the Arduino IDE as something "only hobbyists use" says more about the person making the comment than about the IDE itself.

After all, engineering isn't about proving how sophisticated your tools are.

It's about building products that work.
