What’s the difference between a microcontroller and a microprocessor?
There is no hard definitions and many devices blur the distinction, but these are general guidelines: A microcontroller is designed to be self-contained device that can be used to control a wide range of machines. In this context it is called an embedded controller. In addition to the processor, a microcontroller will include program and…

What difference does 32 bits really make?
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,…

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,…

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…

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…

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…

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…

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…
