RPi

The Raspberry Pi(RPi) is a series of small single-board computers. One powerful feature of the Raspberry Pi is the row of GPIO (general purpose input/output) pins along the edge of the board.These pins are a physical interface between the Pi and the outside world. At the simplest level, you can think of them as switches that you can turn on or off (input) or that the Pi can turn on or off (output). Some pins on RPi also perform some alternate functions.

We are using RPi 3B for our purpose.

Before you can power up your Pi, you will need to program in the SD card with an Operating System. Much like your computer has Windows, Mac OS X or Linux on it to make it run, the Raspberry Pi needs something to help it boot and run software. Raspbian is a free operating system based on Debian optimized for the Raspberry Pi hardware. We have used Raspian Jessie for our purpose.

You can get the latest version of Raspian Jessie from the Raspberry Pi downloads page: https://www.raspberrypi.org/downloads/

Then you need to install operating system images into your SD card. For downloading the image and then writing it onto your SD card refer the installation guide- https://www.raspberrypi.org/documentation/installation/installing-images/README.md

SET UP YOUR LOCAL NETWORK -Make sure your Raspberry Pi is properly set up and connected. You can use both the wireless/ wired network. We used the wired mode.If you are not using wireless connectivity, plug your Raspberry Pi directly into the router. You will need to note down the IP address of your Pi in order to connect to it later. Using the ifconfig command will display information about the current network status, including the IP address, or you can use hostname -I to display the IP addresses associated with the device.

SSH(Secure Shell)- You can access the command line of a Raspberry Pi remotely from another computer or device on the same network using SSH. For exact procedure related to accessing the command line of your RPi refer to- https://www.raspberrypi.org/documentation/remote-access/ssh/

You only have access to the command line, not the full desktop environment. For a full remote desktop, see VNC. Sometimes it is not convenient to work directly on the Raspberry Pi. Maybe you would like to work on it from another device by remote control.

VNC is a graphical desktop sharing system that allows you to remotely control the desktop interface of one computer (running VNC Server) from another computer or mobile device (running VNC Viewer).

Enable your VNC server either graphically or using terminal. Then connect it to your RPi with VNC viewer.
