Open source code

Arduino offers Open Source code, which means that it is completely free in terms of downloading and using the platform and also programming the microcontroller.

One of the most important issues regarding Open Source programming is that any licence is required to obtain the software package.

Plenty of libraries

Thanks to all the Arduino users in the world, a lot of libraries have been created to make some tasks easier.

Since everything is open source, everyone can access the libraries.

Big Community

Arduino technology has attracted a wide range of users, creating a large community that draws new members.

Thanks to this, a multitude of tutorial websites and forums have been created and Arduino also provides a forum where users can comment and discuss about programming issues, doubts and so on. Here you can find the main forum page:

Inexpensive

The prices of Arduino products are very affordable compared to all functionalities and offer good value for money.

Versatility

Ladder programming is the most popular programming tool in the industrial environment, with CoDeSys being the most widely used programming language.

Although Ladder is limited because most blocks cannot be customized, it is also easier to use thanks to its intuitive design.

Arduino board allows the user to program it using its own platform: Arduino IDE, or even with C++.

Modular

Due to the limitations of the basic Arduino board, shields have been designed to fit all types of Arduino boards to implement and add new functionality to the product, such as an Ethernet shield, communication shields or even custom shields for specific communications and protocols.

Electromagnetic noise

Electromagnetic interference (EMI) is unwanted noise in an electrical path or circuit caused by an external source. This can affect the output values of an Arduino pin or cause erroneous voltages to be read from an input.

Vibrations

Vibrations can be detrimental to all Arduino boards, as they can affect GPIO reading/writings and can also reset the program, which can be a problem of no return if it is dedicated to a critical part of the system.

Low IP protection

The Arduino design makes the board fully unprotected against all types of materials and environments, so the microcontrollers must be kept in a safe place all time.

No Technical Support

The Arduino company does not have a Technical Service, which makes it difficult to communicate with the manufacturer. The alternative to solve the doubts is to join the community.

No certifications

Products sold on arduino.cc do not have a specific industry certification.
