2. Raspberry Pi • Credit card sized computer • €32 • Made in the UK • 6 million sold
3. Raspberry Pi Community
4. Raspberry Jam
5. Raspberry Pi Setup
6. What do I need? • USB mouse • USB keyboard • USB power supply • Monitor or TV • HDMI cable • Micro SD card
7. Optional extras • Case • Ethernet cable • USB WiFi dongle • Camera module • USB Bluetooth dongle • Speakers or headphones
8. The SD Card • This is your hard drive – Operating system – Files + programs
9. Getting started • Insert SD card • Connect mouse & keyboard • Connect HDMI cable • Connect power supply
10. 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
11. Sonic Pi
12. 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
13. 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
14. Mathematica • Expensive proprietary software – free on Raspberry Pi • Powerful scientific programming
15. Physical computing • Flashy lights • Motors & robots • Photo & video • Sensors • Internet of Things • Engaging and empowering
16. GPIO Pins – General Purpose Input/Output rasp.io
17. 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)
18. Flash an LED • “Hello world” program of physical computing
19. 3V3 = always on
20. GPIO = user controllable
21. 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)
22. Traffic Lights green.on() yellow.off() red.off() sleep(10)
23. Traffic Lights green.off() yellow.on() sleep(1)
24. Traffic Lights yellow.off() red.on() sleep(10)
25. Traffic Lights yellow.on() sleep(1)
26. Traffic Lights green.on() yellow.off() red.off()
27. Pi in the Sky
28. The sky is the limit...
29. ...or is it?
30. Astro Pi
31. Sense HAT • 8x8 RGB LED matrix • Mini joystick • Gyroscope • Accelerometer • Magnetometer • Temperature sensor • Barometric pressure sensor • Humidity sensor
