Installing Raspbian
If you do not already had an SD card preloaded with Raspbian, the cheapest way to get it is to download it on to a Micro-SD card. This requires that you have access to another computer.
- In your non-Pi computer, insert the SD card into either the built in SD card reader or a USB card reader.
- Go to the Raspberry Pi Downloads page (click this link).
- Select the tab RASPBIAN.
- Select the LITE Download Zip option.
- Save to your desktop and unzip the folder.
- To write the .img file to the card, download and install Etcher and open it.
- Select the .img file, select the SD card, and hit "Flash!"
- Remove the SD card and insert it into your Raspberry Pi, as shown below.
Hardware Configuration
Network connection
To connect to the internet, you can either:
- Plug an Ethernet cable into the Ethernet port:
- The Raspberry Pi has an Ethernet port, together with the USB ports. Plug one side of the Ethernet cable into the Raspberry Pi and the other side into a router. Now the Raspberry Pi will automatically connect to the internet.
- Connect a WiFi dongle to one of the USB ports:
- Plug one Wifi dongle into the raspberry pi and another into your computer. You should now be able to access the wifi just like you would on a normal computer.
- In the top right corner of the screen, you should see a wifi configuration symbol. Click on it and select your network.
- You should now be connected to the network. If not, repeat steps B1-3.
GPIO Pins
If you require input to your Pi for you project, here's a handy diagram of the different pins available on the Pi 2 and 3:
Be very deliberate in plugging things into your Pi; playing around with random wires and pins or things that require lots of power can wreck your device.
