Raspberry pi noobs

we’re going to learn to be at least dangerous in the use of the raspberry pi, the raspberry pi is a credit card size computer it may be small and cheap but it’s not a toy you could do some powerful things by learning how to control it and there’s a growing list of projects and achievements on record the PI has even gone into space control the PI and at the same time,

Raspberry pi noobs you’ll learn how to operate the very largest computers in the world 498 of the top 500 systems in the world use the same system, they’re all based on what will be shown here now because of the way technology is changing so rapidly it’s highly likely that everything I now say is going to be out of date before it’s even uploaded onto the web well perhaps not that quickly but do try to seek out the very latest information on all of the areas covered here the Raspberry pi noobs is also an example of how rapidly technology is changing this new edition of videos has been rewritten for and is based entirely on the Raspberry pi noobs model B in the last 4 years since the PI 1 was introduced it has gone from a version that ran a single core of 700 megahertz to one that now runs 4 cores at 12 hundred megahertz 1.2 gigahertz it’s memory size has quadrupled from 256 megabytes to one gigabyte and now has built-in Wi-Fi and Bluetooth radio now you don’t need to understand all of this at present but what it does mean it’s now easier to use and 10 times faster than it was before without having increased in price in just four years over 8 million units have been sold which makes it now Britain’s most popular computer, as a bonus it’s manufactured just up the road by Sony in Bridgend during these videos we will use this red arrow to indicate particular items and drop important keywords down as shown and display an exclamation mark to highlight really important stuff very occasionally there will be data bursts of a channel information inserted into the video, Raspberry pi noobs, I hope they’re helpful and not too disturbing so where to begin lightning is the discharge of millions of volts across the sky it started life that can be a killer on a smaller scale you may have noticed small cliques when you touch metal surfaces or noticed your hair fizzes up when you’ve wear man made, Raspberry pi noobs, fibers like nylon this is also caused by static electricity and can destroy electronic circuitry it’s why the spice applied in a special protective plastic bag before touching the Raspberry pi noobs or any other device you should earth yourself by touching a bare metal water pipe or central heating pipe even then you should try to avoid touching any connections and hold boards by their edges another thing to be careful of is shorting out any terminal connections with a metal object let’s have a closer look at the Raspberry pi noobs the green printed circuit board PCB is made of fiberglass and is referred to as the motherboard as it looks after all of its components like a mother the first thing to notice is how much space is taken up by connectors each is labeled in white on the board on the right here are a pair of USB connectors each connector accepts two USB plugs below these is an rj45 network port labeled Ethernet the earpiece headphones or speakers socket is here a camera may be connected here and an HDMI monitor connects here HDMI stands for high-definition media interface the power is supplied by this small microUSB connector labeled PWR in and another display can be connected here finally there are these 40 pins which make up what is called the GPIO the general purpose input output this allows you to connect other electronic devices as we will see shortly on the other side of the board is a micro SD socket for the memory card if we bank out all of the sockets it leaves us with the components that do all the work if we superimpose a heat photograph pie the white sections show the hot areas this shows us that it’s this device that does all of the work or one that gets hot anyway it is what is known as the SOC the system-on-a-chip the main part of this is the four processor cause the brains inside the pie that do all of the calculations this other chip makes the connections through the USB and networking ports the Wi-Fi and Bluetooth antenna is this device and this group of devices conditions the power supply there are two LEDs on this board a red one that is on when the power is supplied and a green one that sleigh would act for activity on the other side of the board is this memory chip and a group of components to control the Wi-Fi and Bluetooth radio signals the board is green as this is an insulating layer under this for the lines that are the tiny copper tracks that make the connections between the devices these tracks are on both sides of the board and these dots are tiny holes that take the signal through the board just to complicate things even further there are two more layers of connections sandwiched inside the board as you can see on this diagram there’s a lot to this little pie the pie can be used on its own connected to other components using the GPIO or connected to other boards or even a touchscreen this one has been included in the dashboard of a car nothing happens if you just plug in a Raspberry pi noobs you have to insert a memory card first and this card has to contain the data that provides it with an operating system one available option turns your pie into a PVR a personal video recorder which can cost over 150 pounds if you purchase it from an electronic store another allows you to run old computer games the Raspberry pi noobs can run Android which makes it look just like a mobile phone you can add Windows but why would you when you have something even better it’s called linux and here is tux it’s mascot it’s a software we refer to when we mentioned the control of the 498 applications on the top 500 machines in the world this chart shows how popular linux is the version of linux ported to the Raspberry pi noobs is called raspbian and Linux is a tribute to what can be achieved when the community shares it began in 1991 when a Finnish student leanest Torvalds posted this invitation to join in on an idea he’d been working on as a hobby the idea was to rewrite an operating system based on UNIX but usually ran on machines the size of rooms turn these machines on and the street lights dimmed he wanted to run it on his PC it was a massive task but it all went viral today it’s the single most popular operating system by far you may not recognize the Lang Linux but it has been used everywhere not just large computers but tablets and watches too it is the operating system of choice it also forms the basis crucially it is what is known as false free and open source software open source means that you can actually see download modify and run your own copy of the code and it’s free this is a powerful idea that we will be using on all of the software on this course there are many flavors or distributions of Linux that various groups publish the version this course uses is based upon Debian as it’s used around the Raspberry pi noobs it’s called raspbian we supply these cards to get you started but in the spirit of this course we encourage you to make your own this is covered in a later video connecting up the Raspberry pi noobs shall be relatively simple but I’ve watched in amazement a students attempt to poke any plug into any socket consider the Raspberry pi noobs a high-tech shape-sorter look at the plug look at the sockets and the labels on the PCB each connector will only go in one way round the first the gold fingers go in first and should directly face the PCB in older devices this would click into place but the Raspberry pi noobs just appears to grip the card next insert the mouse and keyboard these go into any two of the four USB sockets which ones don’t matter the rj45 network plug does click into place into the Ethernet socket the small clip on the bottom of the plug has to be squeezed to release it from the socket don’t just try to pull it out if you have earphones headphones or speakers then these plug in here this plug is the same type is that use on mp3 players it’s called a 3.5 millimeter jack and you can forget that fact immediately insert the flat HDMI plug into the HDMI socket it’s advisable to ensure that your monitor is already connected plugged in and turned on before the power is added to the pie finally the power supply plug should also be familiar as it’s the one used to charge mobile phones it’s advisable to turn on the powers of the power supply and then insert the plug into the Raspberry pi noobs does not have a reset or power button inserting the power is all that’s needed to start it if all is gone well the red LED on the PCB should come on followed by the green activity light that should flash as the memory card is red a multicolored square appears on the monitor followed by four Raspberry pi noobs logos a stream of gobbledygook then flies up the screen as the Raspberry pi noobs goes through its boot process you could also check the yellow light on the rj45 connector illuminates to prove the connection and the green LED flashes to show activity on your network at the end of the boot process you will either see a text login prompt or a graphical desktop if you see a text login enter in lower case the username Raspberry pi noobs and press the Enter key the password challenge appears so enter the password again all in lowercase the default password which is Raspberry pi noobs with a P / security reasons the password is not shown on the screen press ENTER again this prompt appears typed startx followed by enter after a few seconds the graphical user interface should appear we are now all at the same place with this Raspberry pi noobs desktop you can click on this icon to see what is known as the command-line interface the CLI this is known as the prompt commands are just typed in followed by the enter or return key it is a simple but powerful interface that we will explore further in forthcoming videos the desktop is a graphical user interface GUI or GUI as is pronounced when you finish investigating click on the menu button and click on this option from the drop down menu click on shutdown from this end session window and press ok this surprisingly shuts the Raspberry pi noobs down we used to say wait until the green LED stops flashing before removing the power but the latest version of software seems to leave this green LED on permanently so insert a memory card first and this card has to contain the data that provides it with an operating system one available option turns your Raspberry pi noobs into a PVR a personal video recorder which can cost over 150 pounds if you purchase it from an electronic store another allows you to run old

Raspberry pi noobs down we used to say wait until the green LED stops flashing before removing the power but the latest version of software seems to leave this green LED on permanently so wait until the screen goes blank and then remove the power only then remove the memory card two things to note don’t just remove the power at any point shut the Raspberry pi noobs down cleanly as shown here you using the shutdown command don’t remove the memory cards until the Raspberry pi noobs has shut down if you do you may lose your data or the system may become corrupted and unstable we’ve covered a good deal in this video we introduced the credit card sized Raspberry pi noobs computer in particular,

The latest version raspberry pi noobs 3

Raspberry pi noobs

we saw how care has to be taken when handling any electronic circuitry and took a tour of the board with this connectors we also saw the location of the important onboard LED indicators we saw that the Raspberry pi noobs can take on any personality in some form it can look like a personal digital video recorder or music streamer it can run Android or Windows but the preferred option is raspbian which is the version of free and open-source software operating system Linux that we’ll be using in this course it’s Linux that turns this small cheap device into a system that is used in exactly the same way as much larger or more powerful machines use skills learnt on the Raspberry pi noobs are transferable to the biggest systems in the world the PI is also a gateway to a wealth of free and open source software and all of the sites that exists to help users run their software process of inserting the memory card connecting and powering up the Raspberry pi noobs was followed with a view of the boot process once logged in the two views of the PI was seen the CLI the command-line interface and the GUI Lagoo II finally the process of cleanly shutting down the Raspberry pi noobs removing the power and then the memory card was covered this sequence was necessary to help ensure that how data remains valid now that we know how to connect power up and shut down cleanly we can move on to discover some of them all useful things we can do with the Raspberry pi noobs you
