11. 6 Million Raspberry Pis sold • Minor revisions • Model A • Model B+ • Model A+ • Raspberry Pi 2
12. Education • Hired education team • £1m Education Fund • Picademy - free teacher training course • Free learning resources • Improvements to software
13. Raspberry Pi Setup
14. What do I need? • USB mouse • USB keyboard • USB power supply • Monitor or TV • HDMI cable • Micro SD card
15. Optional extras • Case • Ethernet cable • USB WiFi dongle • Camera module • USB Bluetooth dongle • Speakers or headphones
16. The SD Card • This is your hard drive – Operating system – Files + programs • Buy pre-installed or download and install using your PC • NOOBS (New Out Of the Box Software) – Easy installer – Drag & drop – Contains Raspbian • Raspbian – Full operating system – Lots of useful software pre-installed
17. Getting started • Insert SD card • Connect mouse & keyboard • Connect HDMI cable • Connect power supply
18. Booting the Pi • Boot messages are shown • Learning opportunity – What's happening? – Are there any errors? – Encourages questions • Pi 1 = 1 Raspberry Pi 2 = 4 Raspberries Why? (hint: single core vs. quad core)
19. Logging in username: pi password: raspberry Note: password not shown when typing
20. Command line • The Pi is ready and awaiting your command!
21. startx To boot to Desktop – and a full Graphical User Interface (GUI), type the command startx and press Enter Note: You can configure the Pi to boot to Desktop or boot to the command line
22. The Terminal • A window with a command line prompt • Enter commands to run while you're using the Desktop
23. raspi-config Open a Terminal window and enter sudo raspi-config sudo means “super user do” - runs the command with administrator privileges
24. raspi-config • Enable boot to Desktop • Internationalisation – Locale – Timezone – Keyboard layout • Enable camera module
25. Main Menu • Launch programming applications • Web browser • Preferences and settings • Shutdown & reboot
26. Internet connection • Connect ethernet cable before boot and it just works • Connect ethernet cable after boot usually works too • WiFi dropdown menu • Check your IP address – Hover over WiFi icon – hostname -I (in terminal)
27. Scratch • Drag & drop block interface to programming • Logic • Computational thinking • Easy to make games • Impossible to create a program that fails to run! • Recommended for young children
28. Sonic Pi • Sound synthesiser for creating music • Audible computing • Uses simple syntax text-based programming language Ruby • Used for compositions and live coding performances • Introduce computing concepts through music • Created especially for education
29. Python • Powerful extensible programming language • Easy to read and write • Make software, games, GUIs, websites, robots and more • Ideal for physical computing • Extensive library of additional modules for Raspberry Pi hardware • Recommended for education
30. Minecraft: Pi Edition • Free version of Minecraft on Raspberry Pi • Python programming interface • Learn Python by building things and making games in Minecraft • Creative computing
31. Mathematica • Expensive proprietary software – free on Raspberry Pi • Powerful scientific programming
32. Physical computing • Flashy lights • Motors & robots • Photo & video • Sensors • Internet of Things • Engaging and empowering
33. GPIO Pins – General Purpose Input/Output rasp.io
34. Python library - RPi.GPIO • Included in Raspbian • Features: – Configure pins as input/output – Read inputs (high/low) – Set outputs (high/low) – Wait for edge (wait for input to go high/low) – Pin event detection (callback on input pin change)
35. Scratch GPIO • Third-party download gives access to GPIO pins • Soon to be implemented in default Scratch • Drag & drop programming for robots and more!
36. Flash an LED • “Hello world” program of physical computing
37. 3V3 = always on
38. GPIO = user controllable
39. Flash LED with Python from RPi import GPIO from time import sleep GPIO.setmode(GPIO.BCM) led = 2 GPIO.setup(led, GPIO.OUT) while True: GPIO.output(led, True) sleep(1) GPIO.output(led, False) sleep(1)
