What makes Arduino so popular?

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… Continue reading What makes Arduino so popular?

What current can Arduino provide?

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).

How is Arduino powered?

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… Continue reading How is Arduino powered?

How does Arduino differ from Raspberry Pi?

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… Continue reading How does Arduino differ from Raspberry Pi?

What does it mean that Arduino is an open hardware device?

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… Continue reading What does it mean that Arduino is an open hardware device?

Can Arduino be connected to a computer?

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… Continue reading Can Arduino be connected to a computer?

What languages can be used for programming Arduino?

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… Continue reading What languages can be used for programming Arduino?

What is an Arduino Shield?

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,… Continue reading What is an Arduino Shield?

What accessories can be used with Arduino?

Arduino boards have analog and digital pins to which you can connect many other electronic components and devices, including displays, motors and sensors. Arduino Shields also allows you to extend the functionality of the board by adding options such as a Wi-Fi or Ethernet interface. There are also pin expanders to increase the number of outputs. The… Continue reading What accessories can be used with Arduino?
