The answer to this question depends on the quality of the clones. Arduino is open-hardware – this means that anyone can legally build their own Arduino or create a compatible device. However, before you buy a device, you should check if it is an original board or a fake or just a device that is compatible…

The Arduino board is characterized by a careful design and excellent parameters. It also has a relatively low price, especially compared to other similar devices. Also important is the large number of compatible elements, including other devices, extensions and accessories. Moreover, Arduino is easy to program, which makes it a particularly friendly solution for these…

Analog and digital pins allow you to draw about 40 mA per pin, while the 5 V pin allows you to draw a maximum of 1 A (this depends on the power supply used and the amount of power supplied by the source).

The board can be powered via a USB interface as soon as it is connected to a computer or via a DC switching power supply with a 5.5 mm x 2.5 mm or 5.5 mm x 2.1 mm plug. The second solution is especially recommended for projects with higher power requirements, e.g. some projects using motors or…

While both devices are referred to as minicomputers, Arduino and Raspberry Pi are quite different. The main difference is their purpose. Arduino works best as a controller for analog systems, e.g. motors in mechanical devices, or for receiving and transmitting data from analog sensors to the display. Meanwhile, Raspberry Pi is a more complex device, better suited for working with…

This means that Arduino devices are not protected by patent law – they can be copied and distributed (even commercially), and their schematics are provided free of charge by their creators. Arduino clones include i.e. Freeduino boards and shields that are compatible with the original devices. You should keep in mind that – even if the devices can be…

Yes, most Arduino boards support UART and USB interfaces, so you can connect them to a computer and then use it to configure or program your board. Your computer can also become the central module of a larger system combining several Arduino boards and other electronic components, for example in a home automation system. In this example, Arduino boards…

The Arduino programming language is based on the Wiring environment and is therefore similar to C and C++. Once you have connected the card to the computer and configured it correctly, you can also use other programming languages such as Java, C #, ActionScript, Perl or VBScript, so that you can choose the environment that you find most…

Arduino Shields are expansion modules intended for use with the Arduino board. Since the name “Arduino Shield” is reserved, it can only be used in relation to the original accessories released by the authors of Arduino. Among the shields you will find e.g. controllers for motors and servos, keyboards, displays, sensors, loudspeakers, microphones, measuring devices, communication interfaces,…
