The phrases “8 bits”, “32 bits”, and “64 bits” are seen quite frequently these days, but what do they really mean? They mean that microcontroller’s internal pathways can carry that many bits of data at the same time. At the very least, this means that whenever a 32-bit microcontroller wants to get information from memory,… Continue reading What difference does 32 bits really make?

What’s the difference between AVR and ARM?
Both AVR and ARM refer to families of devices. The ARM architecture was developed by the ARM company and is licensed to other companies, while the AVR architecture was developed by Atmel and pretty much stayed within Atmel (now owned by Microchip). Both AVR and ARM are microprocessors. AVR never appears as a stand-alone microprocessor,… Continue reading What’s the difference between AVR and ARM?
Introduction
The original Arduino family of boards was based on Atmel AVR 8-bit microcontrollers. These devices are excellent in terms of price, flexibility, and ease of use, but the limited processing speed and small memory size make it difficult to support modern networking protocols. Arduino has taken advantage of the availability of low-cost 32-bit microcontrollers based… Continue reading Introduction
Is it worth investing in Arduino clones?
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… Continue reading Is it worth investing in Arduino clones?
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?
