Introduction to the Raspberry Pi ® Saman Amighi 10/2013 ® Raspberry Pi Foundation

Raspberry Pi Created by the Raspberry Pi Foundation Built to be an educational tool Credit Card size computer Linux Based Can be powered up with existing power supplies or batteries

Raspberry Pi Function It can Be used as programming tool Drive electronic components Be a 24x7 Linux system Be networked with most any device (and to each other) It can’t Run windows as is With some handy work, it can run Windows 95!

Raspberry Pi Key Parts Ports USB (1/2) Keyboard Mouse Power (microUSB) SD Card HDMI or TV Video Network/LAN (100) Other GPIO pins Audio Jack Status LEDs

Raspberry Pi General Purpose Input Output (GPIO) Key Pins 1 – 3.3 V 2 – 5 V 6 – Ground 7 – GPIO4* 13 – GPIO21/27

Raspberry Pi First steps Purchase Raspberry Pi Purchase Components Create SD card Boot up initial Image Login

Configuration bootup Quick-start-guide information Create SD card image Assemble Do not power up yet!!! Insert SD Card Connect HDMI or TV OUT Connect Keyboard/Mouse Connect Ethernet/Network Ensure Monitor and Network are powered up Connect power to the Raspberry Login – pi/raspberry

Initial Screen

Next Steps Decide on a project Which project do you want to work on? Electronics – 3 hours - $50 Media Center – 3-5 hours - $30 Linux box with 100% up time – 1 hours - $0 Printer Server (CUPS) – 1 hours - $0 NAS – 3 hours - $100 Laptop (Atrix Lapdock) – 3 hours - $100

Rasberry PI Initial steps as a native Linux box Raspi-config Set date, time, timezone change local settings for keyboard and OS Set SSH on (9/25 version has it on) Change pi password apt-get update apt-get upgrade apt-get install xrdp

Next Steps Linux Box Initial tasks (cont’d) Enable wireless if using a dongle (see next slide) Ifconfig –a (ensure you have network IP Address) Ex: SSH from a windows or mac system Windows – download and use putty Mac – open terminal – ssh If rdpx was installed – use RDP and IP Address Windows – enable windows Remote Desktop Mac – install Microsoft Remote Desktop

Class Activity – Session 1 (30 minutes) Track I – Raspberry Pi Intro Use one of the Raspi laptops or your own machine to build the initial SD card See instruction sheet next to Raspi laptops Identify the ports on the Raspberry Pi and plug in the components Power up and observe Track II – Linux Login to the console Or login remotely Track III – GPIO Intro LCD display power up and review

Class Activity Session 2 (30 minutes) Track I – Raspberry Pi Raspi-config to set the local time Identify components using Linux commands Track II – Linux Clone SD card and test Track III – GPIO Connect two Pis via Console cable Wire the LCD and get it operational

Next Steps At home Pick a project Samba (network file servers); Media Server; simple GPIO LED project (see sister Arduino) Purchase the Raspberry Pi; Purchase necessary components Do research and bookmark specific parts Packages (software) needed Components, wiring diagrams Review posts Complete the project Take pictures so you remember how it worked !!!

Recommendations Have multiple components handy and if possible multiple Pis Test an image and save it often (rpi-clone) Read the forums before purchasing new boards, components me with questions or pictures of completed projects Contact me with interest in new projects Using meetupl.com for this event

Q&A Raspberry Pi general question? Linux or Raspbian questions? GPIO questions? Electronics questions?
