This article mainly shows you the "sample Analysis of Arduino and Raspberry Pi", which is easy to understand and clear. I hope it can help you solve your doubts. Let the editor lead you to study and learn the article "sample Analysis of Arduino and Raspberry Pi".

1.3 introduction to other mainstream open source hardware

There are many kinds of open source hardware, but there are two main types of open source hardware that are often compared with BeagleBone. They are Arduino and Raspberry Pi (raspberry pie). They are often compared because they have both similarities and differences. In the author's opinion, they can complement each other, but they are irreplaceable.

1.3.1 Arduino

Arduino is often used to refer to the hardware controller board of Arduino. Strictly speaking, Arduino represents a complete system of software, hardware, community and sharing spirit. In view of the positioning of this book, the author temporarily uses Arduino to represent the controller board of Arduino. Arduino is smaller than Beaglebone Black and is an Arduino compatible board as shown in figure 1.2. this article is selected from the BeagleBone Black Quick start tutorial.

Arduino mainly takes the microcontroller of Atmel as the core, and defines a set of standard interface specifications, coupled with a rich function library, it can easily drive a variety of sensors and actuators. Arduino has the following main characteristics:

Q the price is low

Q there are abundant shield plates that can be used directly.

Q comes with IDE, free and open source

Q hardware is open source, capable users can redesign the circuit board according to their own needs

Q-rich third-party libraries make it very easy to drive some devices, such as steering gear.

Of course, due to the limitations of hardware, Arduino can not complete some heavy computing tasks such as video capture. However, it is sufficient to complete slightly complex projects such as tracking robots and remote control models.

So, in terms of focus, Arduino is more hardware-oriented. In other words, it is of little use if it is not used in conjunction with some electronic devices.

1.3.2 Raspberry pie Raspberry Pi

Raspberry pie is designed as a low-cost computer to teach students how computers work and programming languages. Therefore, it is equipped with commonly used computer peripheral interfaces, including audio and video interfaces, HDMI and two USB interfaces. Although the raspberry pie also provides an interface with hardware to drive some sensors, it is more software-oriented. Even without the use of other electronic devices, raspberry pie can achieve most of the design functions. The structure of the raspberry pie is shown in figure 1.3. this article is selected from the BeagleBone Black Quick start tutorial.
