Introduction to: ¡ What’s a Raspberry Pi ¡ What’s in a Raspberry Pi ¡ What’s not in a Raspberry Pi ¡ Raspberry Pi Operating Systems ¡ Introduction to Linux ¡ What’s the GPIO? ¡ What’s a breadboard? ¡ Now what? (Future projects) ¡ A series oF low-cost, single-board, credit card- sized computers ¡ Developed in the UK by the Raspberry Pi Foundation with the intention oF promoting the basic teaching oF computer science ¡ A cool toy to play with and use For project without Fear oF “breaking” things ¡ BlueTooth ¡ Wi-Fi ¡ GPS ¡ Accelerometers ¡ Hard disk (well, kind oF) ¡ Mostly Linux § Raspbian (What we’ll use) § Arch § Kali (Penetration Testing) ¡ Some UNIX § RISC OS ¡ Some specialty § MAME (Multiple Arcade Machine Emulator) § XBMC (Xbox Media Console – Medial Player) ¡ Windows 10 IoT Core ¡ Logging in: § Username: pi § Password: raspberry ¡ The “sudo” command is required For root/ administrator commands ¡ Configuring your Pi § raspi-config ▪ Enable/Disable graphical login ▪ Change password ▪ Enable Camera ▪ Enable SSH ¡ The Pi is not a high-power computer, but does support a GUI ¡ BeFore starting GUI, ensure you have a mouse ¡ Command: startx ¡ Access command-line via the Terminal application ¡ Where am I? § User’s directory is /home/pi § Get back to home: cd ~ § pwd gives the Present Working Directory ¡ Change directory: cd ¡ Make a directory: mkdir ¡ Listing files in a directory: ls ¡ Copy a file: cp ¡ Delete a file: rm ¡ Most commands support -h or --help ¡ Manuals For commands § Can be read by typing man in Front oF the command (e.g. man ls) § Use arrows to navigate and q to quit ¡ Apropos § When you’ve no clue, use the apropos command § Apropos searches manual pages For the words that you ask it about § Try: apropos zip ¡ GPIO lets you power, control and read devices § Motors § Motion Sensors § Cameras § GPS § Motors § LEDs ¡ Sometimes you want to control lots oF stuff ¡ Sometimes you don’t want to solder ¡ Sometimes you just want to play ¡ The breadboard allows For proto- typing without soldering ¡ We can use the Pi as a miniature computer § Firewall § Tor node § Web server § Media server § MinecraFt console ¡ Or…. ¡ We can build cool hardware projects § Motion sensing cameras § Facial recognition biometric locks § Robots § Arcade game Machines ¡ Blink an LED when we receive email ¡ Sibling Alarm § Play a sound when sound when we detect motion in our room ¡ A “Santa Clause” detector § Program the Pi to snap a picture when it detects motion ¡ Don’t panic ¡ Scratch is a graphical programming language (think Legos) ¡ Python is an easy-to-learn scripting language that reads like English ¡ Bring your kids or do these projects at home with them .
