Raspberry Pi: Getting Started !!!
This article will help you to set up your Raspberry Pi (Rpi) for the first time. We need following items to setup Rpi.
Power supply
To connect to a power socket, the Raspberry Pi has a micro USB port (the same that’s found on many mobile phones).
You will need a power supply which provides at least 2.5 amps.
Micro SD card
Your Raspberry Pi needs an SD card to store all its files and the Raspbian operating system.
You will need a micro SD card with a capacity of at least 8 GB. But we recommend 16 GB to make most of Rpi (Installation of many softwares/Setting up build environments etc)
Keyboard and a mouse
To start using your Raspberry, you will need a USB keyboard and a USB mouse.
Once you’ve set your Pi up, you can use a Bluetooth keyboard and mouse, but you’ll need a USB keyboard and mouse for setting up.
TV or computer screen
To view the Raspbian desktop environment, you will need a screen and a cable to link the screen and the Pi. The screen can be a TV or a computer monitor. If the screen has built-in speakers, the Pi will be able to use these to play sound.
HDMI
The Raspberry Pi has a HDMI output port that is compatible with the HDMI port of most modern TVs and computer monitors.
Board Walk-through
Before you connect anything to it, let's take a tour of the board.
4 USB ports:Four USB 2.0 (which means High-speed USB) for connecting keyboards and mouses to. USB 2.0 also handles multimedia transfer meaning USB storage devices and webcams, scanners, and printers.
Ethernet port
Raspberry Pi 3 has a built-in WiFi antenna but you can still hard-wire the Raspberry Pi 3 to the internet through the 10/100 (defines the speed of data transmission) ethernet port.
3.5 mm audio output and composite video
This port does double duty. It supports any speaker or set of headphones with a 3.5mm TRRS audio jack. It also outputs composite video/audio which is the oldest method of carrying a video and audio signal. Found on older screens, it is still widely used for media today. If you would like to output composite video from this port you need to purchase a 3.5mm to RCA cable.
CSI (Camera Serial Interface)
This is the port a Raspberry Pi camera module gets connected to.
HDMI
HDMI (High-Definition Multimedia Interface) is found on most computer monitors and digital TV screens. It supports audio and video and can be configured using the Raspberry Pi's software.
Micro USB Power Input
Where power supplies connect to power Raspberry Pi board. The power supply needs to be +5.1 volts at a recommended 2.5 amps.
Red Power LED
ON when Raspberry Pi is receiving power.
Green Activity LED
Also known as the ACT LED. This goes on when there is activity between the board and the SD card.
DSI (Display Serial Interface)
DSI is mostly used for mobile devices that use LCD screens. You can buy small LCD and touch screens to use with your Raspberry Pi that connect to this port.
Bluetooth/WiFi Antenna
A new addition to a Raspberry Pi board and part of what make the Raspberry Pi 3 stand out from the rest.
40 GPIO (General Purpose Input/Output) pins
Where you connect sensors, switches, motors, and anything else you want to control or sense the world with. You will use and learn more about these in later lessons.
