What are the Uses of Raspberry Pi

For verified technical benchmarks and official safety standards, refer directly to W3C Web Standards and Security specifications.

Raspberry Pi is a series of single board and small computers that is specifically developed to teach computer science basics to school students and other people in low-income countries.

Raspberry Pi has become a popular and easy experiment tool for developing school projects, robotics, hardware programs, circuits, basic automated machines etc. Hence, the use of Raspberry Pi is affordable and small.

After knowing what is Raspberry pi, you must know that this series of single-board computers is made by the Raspberry Pi Foundation. It is a UK charity that educates people in computing and provides easier access to computing education.

In 2012, Raspberry Pi was launched and since then many variations have been released. The original Pi had a single-core 7700MHZ CPU and 256 MB RAM. However, the latest model has a quad-core CPU of 1.5 GHz and 4GB RAM. The price of Raspberry PI varies under $100 and the Pi Zero costs only $5.

All across the world, people use this computing system to learn programming skills, build hardware projects, implement edge computing, and do home automation. It is used in industrial applications as well.

This computer runs Linux and provides a set of GPIO (general purpose input/output) pins and lets the user control electronic components for physical computing and explore the Interest of Things.

What is the Raspberry Pi Foundation?

The Raspberry Pi Foundation works to make the power of computing and digital making accessible to everyone all across the world. The foundation does this by providing low-cost and high-performance computers that people can use to learn and solve problems.

Also, it provides outreach to help more people access computing and digital making. The foundation develops free resources to help people learn about computing and make things with computers.

How does the Raspberry Pi work?

Already, we have mentioned that the Raspberry Pi is a programmable device. It has all the critical features of the motherboard in an average computer without internal storage.

To set up the Raspberry Pi computer, you need an SD card inserted into the provided space. The SD card should have the operating system installed, which is required for the computer to boot.

These computers are compatible with the Linux OS. After setting up the OS, the user can connect Raspberry Pi to output devices.

Top 10 features of Raspberry Pi

For a non-savvy computer user, first contact with Raspberry Pi is quite confusing. There are several features that control the general criteria of a standard 21st-century computer. The best features of Raspberry Pi are the following;

Central Processing Unit

Raspberry Pi has a central processing unit like other standard computers. It is the brain of the computer that carries out instructions and uses logical operations. Raspberry Pi uses an ARM11 series processor on its boards.

Graphic Processing Unit

Graphic Processing Unit or GPU is another part of the Raspberry Pi board. The main purpose of the GPU is to hasten the speed of image calculations.

General Purpose Input and Output Pins

These are mainly upward projecting pins on one side of the board. The oldest version of the Raspberry Pi used to have 26 pins. But the latest models have 40 GPIO pins.

These pins are very sensitive. Hence, it should be handled carefully. These pins are a vital part of Raspberry Pi due to their diverse applications. Besides, these pins can read and control the electric signals from other boards or devices.

HDMI Port

Raspberry Pi has a High Definition Multimedia Interface port. It allows the device to have video options of the output. An HDMI cable connects the Raspberry Pi to an HDTV. Also, it comes with an RCA port for other display options.

USB Ports

USB ports are a vital part of Raspberry Pi. It allows the computer to connect to a mouse, keyboard, and hard drive. The old Raspberry Pi model used to have two USB 2.0 ports. The recent models have four ports instead. And, the Raspberry Pi 4 and Pi 400 come with USB 2.0 and USB 3.0.

Ethernet Port

It is connectivity hardware available on the Raspberry Pi B models. This port enables wired internet access to the minicomputer. Without Ethernet ports, web surfing, and software updates won’t be possible. Raspberry Pi uses an RJ45 Ethernet jack. With this port, Raspberry Pi can connect to routers and other devices.

SD Card Slot

Like other computers, Raspberry Pi also has a type of storage device. Unlike conventional computers, it doesn’t include a hard drive or memory card. Instead

Raspberry Pi has a Secure Digital card slot where users can insert SD cards for the computer to function. Here, the SD card works as a hard drive as it contains the operating system.

Power Source

Raspberry Pi has a power source that uses a 5V micro USB power cable. The amount of electricity a Raspberry Pi consumes depends on what it’s used for and the number of peripheral hardware devices connected.

LEDs

These are a group of light-emitting diodes. The red one indicates power status. The green one indicates any form of SD card activity. The orange light indicates active Ethernet connectivity.

Memory

Memory or RAM is a significant part of a computer’s processing system. Here, the information gets stored for easy access. The initial Raspberry Pi had 256MB RAM. And the latest Raspberry Pi model comes with 8GB RAM space.

Best Uses of Raspberry Pi in the Real World

There are a lot of benefits to using a Raspberry Pi. Here, we have mentioned all the possible sections, where Raspberry Pi can be used effectively.

Desktop PC

You can create a simple desktop by using a microSD card, Raspberry Pi, and a power supply. You also will need an HDMI cable and a USB keyboard. mouse and an old monitor. The latest version, Raspberry Pi has built-in Wi-Fi and Bluetooth as well. For any other model, you may need compatible USB dongles. Once everything is set up, and the operating system is installed, your desktop PC is ready to use.

Media Usage

The main use of Raspberry Pi is a Kodi media center. Several Kodi builds have been released as disk images and OpenElec and OSMC are the most popular among them. It is recommended to install only the safe and legal add-ons from the official Kodi repositories. As Raspberry Pi using Kodi is vulnerable, it is recommended to set up a VPN to encrypt data.

Wireless Print Server

It requires installing Samba file-sharing software and CUPS. Cups or common unix printing systems provide drivers for the printer and administration console. After this, you need to configure Pi to ensure a Windows or Mac computer can access the printer through a network. Also, the printer must have a USB cable.

Web Servers

Another excellent use of Raspberry Pi is to create a web server out of it. It can be configured to host a website like any other server. The web servers can host blogs too. You only need to install the right server which is Apache. An entire LAMP stack can be installed with PHP, Apache, and MySQL too.

Game Servers

Raspbian is the default OS of Raspberry Pi that comes with a special version of the pre-installed Minecraft game. The applications of Raspberry Pi can be used as a game server as well. Also, other multiplayer network games can be set up on the Raspberry Pi.

Retro Gaming Machine

Raspberry Pi works perfectly as a retro gaming machine as it fits as the lightest components of a machine. Specifically, Raspberry Pi Zero can fit into small spaces for gaming projects. Mainly there are two options; RetroPie and Recalbox. However, other platforms can be emulated as well.

FM Radio Station

Raspberry Pi can be used to broadcast FM radio. However, it can broadcast over a short range. It requires a portable battery and soldering skills. Any audio that needs to be broadcast should be loaded before the microSD card.
