Raspberry Pi Introduction and Tutorials

In the post i am telling to you about Raspberry Pi. Here you can explore full information about Raspberry Pi.

What is Raspberry Pi ?

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.

What’s more, the Raspberry Pi has the ability to interact with the outside world, and has been used in a wide array of digital maker projects, from music machines and parent detectors to weather stations and tweeting birdhouses with infra-red cameras. We want to see the Raspberry Pi being used by kids all over the world to learn to program and understand how computers work.

Raspberry Pi Foundation

The Raspberry Pi Foundation is a registered educational charity (registration number 1129409) based in the UK. Our Foundation’s goal is to advance the education of adults and children, particularly in the field of computers, computer science and related subjects.

When you buy a Raspberry pi, you are essentially buying an assembled printed circuit board. It does not even include a power supply or Operating system. Because the RPi just uses standard USB keyboard and mice, most of the setup is pretty straightforward, so you will concentrate only on those tasks that are specific to the Raspberry pi.

Big problem is Slecting a model of Raspberry pi. there are may models of RPi and you are not sure which to use.

If you want a Raspberry Pi for general use, then you should buy a Raspberry pi 3, 3B+ or 2 model B. with four times as much memory and a quad core processor. It will cope with most tasks much better than the Pi Zero or model A+ with single processors. the RPi 3, 3model B+ has the great advantage of having WiFi built in, so ther’s no need for an extra USB WiFi adapter.

Now Raspberry Pi 4 is available. It has 4 GB RAM. We are going to discuss it below in this article.

Raspberry Pi Boards

Raspberry Pi 4

The Raspberry Pi 4 comes with up to 4GB of RAM, dual-band WiFi and dual micro-HDMI ports. It is available at a starting price of $35.

After three years of launching the Raspberry Pi 3, the Raspberry Pi Foundation has launched the next single board computer Raspberry Pi 4, which comes with the same form-factor and starting price of $35 just like its predecessor. The Raspberry Pi 4 comes with up to 4GB RAM, which is four times than that of its predecessors. The RAM now comes in LPDDR4, unlike LPDDR2 used in the previous version. Apart from this, the device comes with Broadcom BCM2711, Quad-core Cortex-A72 (ARM v8) 64-bit processor at 1.5GHz.

The Raspberry Pi 4 comes with dual-band WiFi comprising of 2.4 GHz and 5.0 GHz IEEE 802.11ac. It also has Bluetooth 5.0 and Gigabit Ethernet. Apart from this, there is also a couple of USB 3.0 ports and two USB 2.0 ports. There are two micro-HDMI ports, which can plug two 4K display screens at 60 frames per second.

What is the best OS for Raspberry Pi?

Officially RPi recommended Raspberry Pi  OS (Previously named Raspbian OS) for RPi. Raspberry Pi  OS is a free operating system based on Debian optimized for the RPi hardware. An operating system is the set of basic programs and utilities that make your RPi run. However, Raspberry Pi  OS provides more than a pure OS: it comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation on your RPi. Now Raspberry Pi  OS available in 64 bit.

Raspberry Pi For Internet of things (IoT)

Yes RPi can used in IoT. Because RPi is a SoB- System on Board. RPi support various Operating System. Mostly RPi used as Iot Gateway. The internet of things (IoT) is the rapidly growing network of devices(things) connected to the Internet. the does not just mean more and more computers using browsers, but appliances and wearable and portable technology. This includes all sorts of homes automation from smart appliances and lighting, to security systems and even Internet-operated pet feeders, as well as lots of less practicals and fun projects.

You can program hardware on the RPi?

You can, via the row of pins at the top edge of the board (of the 40, 26 are GPIO pins). By attaching hardware like LEDs, sensors and motors to these pins you are able to interact with them using the Pi. Writing simple programs will allow you to send signals via the pins to control the attached hardware–for example making an LED flash– or to read a signal sent from the attached hardware via the pins–for example to take a measurement from a sensor.

Where does the name Raspberry Pi come from?

Raspberry is a reference to a fruit naming tradition in the old days of microcomputers. A lot of computer companies were named after fruit. There’s Tangerine Computer Systems, Apricot Computers, and the old British company Acorn, which is a family of fruit.

Pi is because originally we were going to produce a computer that could only really run Python. So the Pi in there is for Python. Now you can run Python on the RPi but the design we ended up going with is much more capable than the original we thought of, so it’s kind of outlived its name a little bit.

Can I use the Raspberry Pi 4 as a desktop PC?

The Pi can be run as a budget desktop, providing you have the patience. However, don’t expect the Pi 3 to match a typical PC, it will lag loading heavier websites and, when browsing these demanding sites, having more than a handful of tabs open at once runs the risk of overloading the Pi’s memory–causing a lengthy freeze.

Can I browse the web using the Raspberry Pi 4?

Yes, the latest version of the RPi’s official OS has the Chromium browser, the open-source browser that Chrome is based on. It’s performance is reasonable, as long as you don’t open too many script-laden websites, and there are extensions that allow for smooth playback of video on YouTube and other sites.

Can I use the Raspberry Pi 4 as a media center?

Yes, there are various options if you want to use the Pi 3 as a media center but the most popular choices are the Kodi-based OSes OSMC or LibreElec. The Pi 3 has the added advantage of a slightly faster graphics processor, which the RPi Foundation has said is able to play local H.264-encoded video recorded at 1920×1080 resolution and 60 frames per second. Another advantage is built-in support for Wi-Fi makes it easier to stream content to the Pi, while native Bluetooth simplifies the hooking up peripherals.

Can the Raspberry Pi 4 run Windows 10?

Yes, but it’s nothing like the full desktop version of Windows 10 that most people are familiar with. Instead the Pi 3 runs Windows 10 IoT Core, a cutdown version of Windows 10 that doesn’t boot into the graphical desktop and is designed to controlled via a command line interface on a remote computer. It can only run a single fullscreen Universal Windows Platform app at a time, for example a kiosk app for a retail store, although other software can run in the background.

However, the Pi can act as a Windows 10 thin client, where Windows 10 is run on a server and streamed to the Pi and, with a powerful enough server, the experience can be virtually identical to running a Windows 10 machine.

Can the Raspberry Pi 4 run Ubuntu?

It can run Ubuntu with various desktops, with the RPi Foundation highlighting Ubuntu Mate and Ubuntu Snappy Core as standouts.

How do I keep the Raspberry Pi 4 up to date?

If you’re running the Pi’s official Raspbian operating system then keeping the Pi up to date is relatively straightforward. Just open the terminal and type sudo apt-get update. Once the update is complete, then type sudo apt-get dist-upgrade.

What size micro SD card do I need for the Raspberry Pi 4?

If you’re installing the official Raspberry Pi  OS you’ll need at least an 8GB micro SD card, whereas for the Raspberry Pi  OS Lite you’ll need a minimum of 4GB.
