The Raspberry Pi Chinese name is Raspberry Pi. It is designed for learning computer programming education. It is a credit card-sized minicomputer and its system is based on Linux.
Just like any other desktop or portable computer running a Linux system, there are many things you can do with the Raspberry Pi. Of course, it will inevitably be a little different. Ordinary computer motherboards rely on hard disks to store data, but Raspberry Pi uses SD cards as "hard disks", and you can also connect external USB hard disks. With the Raspberry Pi, you can edit Office documents, browse the web, and play games—even if you play games that require powerful graphics accelerators, such as Quake.
The low price of Raspberry Pi means that its use is more extensive, and making it a great multimedia center is also a good choice. With the Raspberry Pi you can play video and even power it via the TV's USB interface.
Raspberry pie is a toy. For people who like to program and like to use computers to control some toys. It is more power efficient and has less power. Close to embedded systems. Long-term shutdown does not consume a lot of electricity. However, the power consumption is slightly larger than arduio. The raspberry pie is used for education. For children, give fans a platform to access embedded programming and industrial control.
The Raspberry Pi is small, but it is the same thing as an ordinary computer. Most of the things that computers do can be done on the Raspberry Pi. The Raspberry Pi uses its features such as low energy consumption, mobile portability, and GPIO. It is a lot of things that are difficult to do on ordinary computers. It is very suitable.
Raspberry Pi Beginner Tutorial Model:1) Raspberry Pi3 Generation B
2) Raspberry Pizero (including zerow)
The Raspberry pie itself is just a host. To get up and running, there must be accessories.
(1) Power supply
A MicroUSB-enabled mobile phone charger can act as a power source, but the output must be 5V and at least 2A. Charging treasure when the power is no problem.
(2) MicroSD card
The Raspberry Pi does not have a hard disk, and the MicroSD card is a hard disk. Minimum capacity 8G, 16G and 32G cards are recommended.
(3) Display
The Raspberry Pi has HDMI output and the monitor must have this interface. If there is a HDMI to VGA extension cable, then a VGA monitor is also available.
However, the monitor is only needed when installing the system. You can log in later with SSH and you will not need it.
(4) Wireless Keyboard
Raspberry Pi built-in Bluetooth, USB or Bluetooth wireless mouse and keyboard can be used.
Just like a monitor, if the Raspberry Pi is already installed and just serves as a server, the wireless mouse and keyboard may not work.
(1) breadboard (a piece)
(2) Cables (Several)
Note that the cable must be male at one end and female at one end.
In addition, it is best to have some cables that are both male.
(3) LED Diodes (Several)
(4) 270 ohm resistor (several)
1, if the merchant has installed the system, you can skip this step, otherwise you need to install the operating system.
The official operating system is Raspbian, which is a customized version of the Debian system.
2, the official also provides a NOOBS installer, it is recommended to install Raspbian, relatively simple.
3, installation steps:
Download NOOBS.
Format the Micro SD card in FAT format (Operation Guide).
Extract NOOBS.zip to the root directory of the Micro SD card.
Insert the Micro SD card into the card slot on the bottom of the Raspberry Pi, turn on the power, and start the system.
4, under normal circumstances, follow the on-screen prompts, all the way back, you can install the system.
1. After installing the system, the Raspberry Pi can access the Internet (Wifi or network cable). At this point, you have to look at its LAN IP address. You can use the following command.
$ sudo ifconfig
2, then, change the system settings, open SSH login (the default is prohibited).
3, then, from another computer SSH login Raspberry Pi. The following command is executed on another computer on the LAN.
$ ssh pi@ your ip address
The default user of the Raspberry Pi is pi.
Raspberry Pi will prompt you for a password. The default password for pi is raspberry. Under normal circumstances, you can log in to the Raspberry Pi. Then, you can perform various server operations, such as changing the password.
$ passwd
Add pi to the gpio user group:
$ sudo adduser pi gpio
Install Node:1. To run the Node script, the Raspberry Pi must have Node installed. Refer to this article.
$ curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -$ sudo apt install nodejs
2. Under normal circumstances, Node 8.x has been successfully installed.
$ node -v v8.1.0
The touch screen monitor allows the user to operate the host computer simply by touching the icon or text on the computer display screen with his finger, thus getting rid of keyboard and mouse operations and making the human-computer interaction more straightforward. Mainly used in information inquiry in public halls, leading offices, electronic games, song and order, multimedia teaching, air ticket / train ticket pre-sale, etc. The products are mainly divided into three types: capacitive touch screen, resistive touch screen and surface acoustic wave touch screen.
