![OK Let's Get It Working!
1. Boot your Pi and get logged in
a. Plug in your keyboard, mouse, and monitor - we’ll use the GUI for now...
b. Your default credentials are username: pi password: raspberry
c. Open the terminal and enter `passwd` to change the password!!
1. Connect to the internet
a. Connect to the BARN wifi.
b. In the terminal enter `ping google.com` to configm we’re on the net
c. Hit CTRL-C when confirmed
1. Update your entire system
a. In the shell, execute `sudo aptitude update` to get the list of the latest software
b. `sudo aptitude full-upgrade` to actually perform the update
1. Americanize your Pi
a. Run `sudo raspi-config`
b. In Internationalization Options, change Locale to en_US.UTF-8,, Keyboard-Layout,
Timezone, and Wi-Fi country to the US
1. Set up SSH so you can log in without hooking up a keyboard and monitor
a. Get your IP address with `hostname -I` and make a note of this
b. From another computer, try to log in to your pi with `ssh pi@<your-pi’s-IP-address>`
1. When ready, shutdown your pi with `sudo shutdown -h now`

Introduction to Raspberry Pi
- 1. Introduction To Raspberry Pi A Presentation For The Bainbridge BARN May 15, 2016
- 2. About Me Tech enthusiast; hardware and software hacker; particular interest in machine learning Pros: This presentation is free of charge! Cons: No training in computer science, embedded systems design, electrical engineering, software development
- 3. What Is A Raspberry Pi? A cheap, tiny, open-source computer
- 4. What Is A Raspberry Pi? Most of us think of computers as this: Or this:
- 5. What Is A Raspberry Pi? But computers can be much more! ...wait...I mean less!
- 6. What Is A Raspberry Pi?
- 7. What Is A Raspberry Pi? • Costs about $35 • Runs linux as its operating system • Basic ports for USB, monitor, and internet • Wifi and BlueTooth • GPIO pins you can use to connect to other devices
- 8. Why Are People So Excited About The Raspberry Pi? • Cheap and Simple – Enables you to easily add a brain to your project • Powerful – You can run surprisingly demanding applications on a Pi • Open Source – Get all source code, schematics, and data sheets for free • Learning Tool – Learn hardware, linux, and programming all at once
- 9. What Can You Make With A Pi? FishPi: An Autonomous Boat
- 10. What Can You Make With A Pi? Pandora's Box: An Internet Radio Player
- 11. What Can You Make With A Pi? RasPiLapse: A Time-Lapse Photo Dolly
- 12. What Can You Make With A Pi? WeatherPi: A Solar-Powered Weather Station
- 13. What Can You Make With A Pi? Dumb Wired Printer → Wifi Printer
- 14. What Can You Make With A Pi? Smart Garage Door Manager
- 15. What Can You Make With A Pi? A Minecraft Server
- 16. What Can You Make With A Pi? A Weather Balloon
- 17. What Can You Make With A Pi? An Automated Pet Feeder
- 18. Communicating With Your Pi
- 19. Communicating With Your Pi Two basic methods: • Directly plug in a keyboard and monitor • Good for initial setup, but inconvenient • Over the network via ssh • Much better, but... • You need to know how to use ssh
- 20. Communicating With Your Pi Don't fear the command line! • Fast • Powerful • Robust (minimal system resources or bandwidth) • Impress your geek friends
- 21. Connecting Your Pi To The Outside World
- 22. Connecting Your Pi To The Outside World • The simplest way is using wifi, BlueTooth or USB – your Pi already has these built in • But for devices that can't communicate this way, use the GPIO (General Purpose Input and Output) pins
- 23. Connecting Your Pi To The Outside World Connect a LED light... <yawn>...
- 24. Connecting Your Pi To The Outside World Connect a button...
- 25. Connecting Your Pi To The Outside World Switch other hardware on or off...
- 26. Connecting Your Pi To The Outside World Control motors, servos, and steppers...
- 27. Connecting Your Pi To The Outside World Yeah, that’s right – now we’re talking robotics!!! * Important Disclaimer: Raspberry Pis were probably not used to make these robots...
- 28. Connecting Your Pi To The Outside World Best of all, control other hardware through the I2C or SPI interfaces
- 29. Connecting Your Pi To The Outside World • Thermometers • Pressure sensors • Ultrasonic sensors • Accelerometers • RFID Readers • Gyroscopes • Photocells • Magnetometers • Altimeters • Etc, etc... Stuff you can control via I2C and SPI:
- 30. I Have My Pi Working...Now What? • The hardest part: learning linux • But once you know the basics, you'll discover how insanely powerful it is • Start here and here! • You can always get help from your friends at the BARN
- 31. I Have My Pi Working...Now What? • To make your Pi do useful stuff, you'll probably want to know some programming • Python is an excellent place to start, since it is widely used, easy to learn, and powerful • Start here!
- 32. I Have My Pi Working...Now What? • If you want to use the GPIO pins, you'll need to know a little about hardware • Start here!
- 33. I Have My Pi Working...Now What? • Finally, for some neat tutorials on how to use your Raspberry Pi • Get these here!
