Why is Arduino Popular?

Openness

The Arduino hardware and software development environment operates under a comprehensive open-source model, enabling users to explore its inner workings while benefiting from a highly user-friendly interface for developing third-party libraries. This openness empowers everyone to freely utilize, modify, and distribute Arduino. The non-commercial focus of the Arduino community is trusted by its users, fostering an environment where successful designs are shared and enthusiasts contribute their hardware and software designs to the community.

For novice electronics users, this open-source approach offers significant advantages. It not only facilitates a more effective understanding of circuit principles but also provides a wealth of basic function modules within the community. These modules encompass diverse functionalities such as servo control, PID speed control, and A/D conversion, allowing users to easily access and incorporate them into their projects. This has resulted in an increased focus from module suppliers on catering to this market segment, offering libraries and related tutorials for hobbyists.

Furthermore, this open-source model enables users to design uniquely shaped boards to accommodate space constraints or develop their own expansion and master control circuits for specialized applications. Such flexibility not only enhances the versatility and adaptability of Arduino but also empowers users to concentrate on designing the specific features they desire, rather than being limited to programming basic functions. This fosters a thriving ecosystem of innovation and customization, driving further advancements in the Arduino community.

Usability

Arduino employs a user-friendly programming language based on C and C++, which makes it accessible even to beginners without prior electronics or programming experience. Its gentle learning curve enables newcomers to quickly embark on their Arduino journey.
