Raspberry Pi

Raspberry Pi is a complete computer, about the size of a large matchbox, that costs around £30. You will also need a keyboard, mouse, screen and power supply. Alternatively, you can buy everything you need, except the screen, as a kit from Maplin. Since the display output uses HDMI, you might be able to use your TV as a screen.

Some kits to allow you to control electronics from your Raspberry Pi are available from SK Pang. The Raspberry Pi can connect to the outside world using its GPIO pins, and you can control these pins with wiringPi.

Minecraft

We’ll be making mods to the Minecraft game using a Rasberry Pi computer.

• Minecraft pi – recipe cards
• Minecraft resources here, including flashcards
• Minecraft book
• Instructions on how to download Minecraft on the Raspberry Pi can be found here

Python and pygame

At BSF in 2013 we did some Python programming using the pygame addon. Here are the original instructions for our Pong game, and here is the Python code plus worksheets for our extensions to the game.

PC Pro magazine has an article on making a Raspberry Pi game in Python.

Another fun Python project is Tux Crossing from Gordons Projects.

Arduino

Arduino is another great system for getting started with programming and electronics. The Arduino software is free to download and there’s a good online reference.

You can get a great starter kit with really good documentation, or a cheaper option: the Arduino Nano. For other kits and components search for “Arduino” on Amazon, eBay or other.

Scratch

Scratch is a fun programming environment for learning. Programs are made by dragging and dropping colourful elements of a computer program onto the screen.

Download Scratch version 2, or the older version 1.4. With Scratch 1.4, you can use Remote Connections.

Here’s a great set of video tutorials, or read about how to control hardware using Scratch. Discover how to connect Scratch to Arduino.

At BSF in 2013 we used some projects from the Raspberry Pi Education Manual (PDF).

Other fun software

Construct 2 is a great free program that lets you create fun games that run in a web browser, and on some mobile devices. We showed Construct 2 at Brighton Science Festival 2012.

Greenfoot is an interactive environment for learning the Java language.

Want to join up with others to have more fun with Scratch and other languages? Why not look for a Code Club – a national network of after-school coding clubs aimed at 9-11 year olds. See also this article from Wired magazine.
