Raspberry Pi And Its Magic

Introduction

Raspberry Pi is a credit card-sized computer, which plugs into your TV and a keyboard. It is a capable little computer, which can be used in electronics projects and for many of the things, which your desktop PC does, like Spreadsheets, Word processing, browsing the internet and playing games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.

HDMI Cable


Figure 3 - HDML Cable 
 
HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface to transfer the uncompressed video data and the compressed or uncompressed digital audio data from HDMI-compliant source device, such as a display controller to a compatible computer monitor, video projector, digital television or a digital audio device. HDMI is a digital replacement for the analog video standards.
 
USB Power & Cable

Figure 4 : USB Cable 
  1. USB was designed to standardize the connection of the computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to the personal computers, both to communicate and to supply the electric power.
  2. It has become commonplace for the other devices, such as smartphones, PDAs and the video game consoles. USB has effectively replaced a variety of the earlier interfaces, such as parallel ports, as well as separate power chargers for the portable devices. 
RJ-45 Ethernet


Figure 5 : RJ-45 Ethernet 
  1. RJ45 (computers), an unkeyed 8P8C modular connector is used for Ethernet computer network cables (incorrectly referred as RJ45).
  2. Ethernet is a family of the computer networking technologies commonly used in local area networks (LANs) and metropolitan area networks (MANs).
  3. It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3 and has since been refined to support higher bit rates and longer link distances. Over time, Ethernet has largely replaced competing wired LAN technologies such as a token ring, FDDI and ARCNET. 
SD Card


 Figure 5 : SD Card 
  1. Secure Digital (SD) is a non-volatile memory card format developed by the SD Card Association (SDA) for use in the portable devices.
  2. The standard was introduced in August 1999 by the joint efforts between SanDisk, Panasonic (Matsushita Electric) and Toshiba as an improvement over MultiMediaCards (MMC) and has become the industry standard.
  3. The three companies formed SD-3C, LLC, a company, which licenses and enforces the intellectual property rights associated with SD memory cards, SD hosts and the ancillary products.
Analog Audio 


Figure 6 : Analog Audio 
  1. Audio recordings are of two basic types- analog and digital. Analog refers to an audio recorded, using the methods, which replicates the original sound waves. Vinyl records and the cassette tapes are the examples of the analog mediums.
  2. Digital audio is recorded by taking the samples of the original sound wave at a specified rate. 
RCA Video Cable

Figure 7: RCA Video Cable 
  1. Composite video (one channel) is an analog video transmission (without audio), which carries the standard definition video typically at 480i or 576i resolution. Video information is encoded on one channel, unlike the higher-quality S-video (two channels) and the even higher-quality component video (three or more channels).
  2. Composite video is usually in the standard formats such as NTSC, PAL, and SECAM and is often designated by the CVBS initialism, for color, video, blanking and sync or simply as video.
Installing The OS To The Kit
  1. First step is to download the OS in the link.
  2. Click the link or copy the link and download the OS. 
  3. Install the OS to SD Card and fix in the Raspberry Pi and install the OS as usual. 
Connecting the Raspberry Pi To the Computer
  1. The laptop needs to have Windows 10 OS. Connect the power cable to the port and another side to the computer.
  2. Connect Ethernet cable also to the port and another side of the cable will be connected to the computer.

Connect Raspberry Pi with SH Terminal

 
Figure 12 : Putty Secction 
  1. Open Putty.exe
  2. Select the port no as 22 and select the SSH radio button.
  3. Type the IP address of Raspberry Pi found out from the IP scanner in the previous step.
    The terminal will be opened.
  4. default login for Raspberry Pi is : pi
    password: raspberry
  5. Now, type the commands, mentioned below.
    1. $ sudo apt-get update  
    2. $ sudo apt-get install tightvncserver  
  6. After successful installation of the tightvncserver, type the commands, mentioned below to start VNC Server.
    1. $ vncserver :1  
  7. You will be prompted to enter and confirm a password. This will be asked only once, during the first time setup. Enter a 8 digit password and make a note of it!
Connect the  VNC Server
  1. Open the VNC Server program.
  2. Now, type the IP address of Raspberry Pi and amend it with :1
    example 192.168.137.20:1 ( This tells the port number).
  3. Now, click connect and another Window will pop up and will ask you to enter the password.
