Previously, when setting up older Raspberry Pi models with older operating systems, we initially needed to hook up a monitor and keyboard in order to let the Pi connect to our wireless network and enable something called SSH so we could login from another computer. There are just two more steps to set up in order to have the Raspberry Pi automatically join your wireless network. You should also see it appear in your list of drives connected to the computer either in Finder (macOS) or File Explorer (Windows). Once complete you should now have a fresh installation of Raspbian Stretch on your micro-SD card. Writing to the SD can take a few minutes. While that's working away, install and open Etcher. Raspbian comes zipped up in an archive so unzip it by double-clicking. Now your card is formatted we can copy the operating system to it. Once you're happy you have the correct drive, click Format. Before clicking format, be sure you have the correct drive selected, otherwise you could mess up another of your computer's drives. You should see the card's drive letter in the drive box. Once attached, install and open the SD card formatter. If, like me, you only have an standard SD card slot you'll need an adapter and possibly a USB card reader. While everything is downloading, attach your micro-SD card to your computer. Download Etcher - this program let's us 'flash' the operating system to the SD card.This version saves space and takes less time to download and install. I tend to use the Lite version since I don't intend on using the Raspberry Pi for anything else. There are usually two version available: 'with desktop' and 'lite'. At the time of writing, this is Raspbian Stretch. Download the latest version of Raspbian - the standard operating system.

Grab the SD memory card formatter - this simply formats SD cards so we're sure they are clean and ready for our OS.Starting afresh, we need to download 3 things to get going: This is very useful when you consider that swapping operating systems is as easy as changing the micro-SD card installed in the Raspberry Pi.

Rather than using a big hard-drive, the Pi stores its OS on a micro-SD card. Just like any other computer our little Raspberry Pi needs an operating system (OS) to run everything. Just joining us? Make sure you've got everything you need as listed in part one of this how-to guide.ĭownload and install the operating system
