Introduction (The Raspberry Pi)

What is the Raspberry Pi?

The Raspberry Pi is a series of small single-board computers developed in the United

Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer

science in schools and in developing countries.

The original model became far more popular than anticipated, selling outside of its target

market for uses such as robotics.

Introduction (The Raspberry Pi)

Introduction (The Raspberry Pi)

The General purpose input-output (GPIO)

header

The reason why the Raspberry Pi is so popular in

robotics, home-brew projects, schools, etc.. is

the GPIO header

The 40 GPIO pins are found on every Raspberry

Pi and can be individually addressable via

custom written code making it extremely

versatile.

Getting Started (Plugging it in)

To get started you need to plug in the following:

Display

Mouse and Keyboard

Power

MicroSD card

Getting Started (The OS)

The main operating system for the Raspberry Pi is called RASPBIAN

Raspbian comes pre-installed with plenty of software for education, programming and

general use. It has Python, Scratch, Sonic Pi, Java, Mathematica and more.

There are over 30 “flavors” of Raspbian designed for specific use cases like Home Theater

Display, Digital Photo frame, Internet connected Radio Player, Home Automation, Retro

Gaming, etc.

We will show you some of those later.

Getting Started (Downloading the OS)

You can download a free copy of Raspbian OS by

going to https://www.raspberrypi.org/downloads/

Click on the Raspbian icon

Under Raspbian stretch with desktop

Click on the Download ZIP button

Getting Started (Installing the OS)

In order to install Raspbian onto the MicroSD card you

need Etcher.

Go to https://etcher.io/ and download the software.

Getting Started (Raspberry Pi)

Raspbian

Demo

Getting Started (Installing the OS)

Insert the MicroSD card with the provided

adapter into the SD card slot on your laptop

Open etcher and select the

downloaded Raspbian Image

Click on Flash! to upload the

software to the SD card.

Once the upload completes

put the MicroSD card into the

Raspberry Pi

Getting Started (Booting the OS)

Once the MicroSD card has been

inserted into the Raspberry Pi and all

cables are attached go ahead and

plug in the power cable

You should see a rainbow image

followed by Raspbian Boot-up text.
