Page Installing A Lamp Stack. Using a LAMP-based server, you can run some quite complex packages rang- ing from content management systems like WordPress to interactive forums like phpBB.

Page Linux parlance as daemons—will be running in the background. To check that the server is working correctly, use another computer on the network to connect to the Raspberry Pi using a web browser. In the address bar, type the IP address of the Pi to display the default Apache installation page see Figure Page PHP to create an information page for diagnostic purposes. Page Installing Wordpress. For example, some of the most popular news sites in the world are built on a customised WordPress platform.

Page Raspberry Pi to continue the installation. Page WordPress, click the Log In button at the bottom of this page to log into WordPress with the user name and password you chose at the earlier screen see Figure For best results, use the Pi as a headless server, which is a system that runs without a graphical user interface loaded.

Page Introducing Scratch Raspberry Pi. The chief goal of the Raspberry Pi project is to get people writ- ing their own programs, however—and not just adults. The Raspberry Pi Foundation is working to get the device adopted as an educational tool for all age ranges. Page Example 1: Hello World. The stage itself is at the top-right of the window, which is where you will see the program running.

Finally, the middle of the window is where the program itself is constructed. Figure The main Scratch interface, shown running on the Raspberry Pi It also fails to show off the true power of Scratch, which lies in its impressive multimedia capabilities and sprite-handling system. Using the New Sprite option just below the stage on the right side of the Scratch window allows the programmer to add more sprites that can move and play sounds independently.

As this is just a very simple game, the goal should also be simple: to collect some food. As you can see, when the two sprites meet, nothing happens. The latter is supported by the Raspberry Pi. Page Robotics With Lego MIT also runs a user forum for Scratch, allowing enthusiasts of the software to learn together and share solutions for common problems.

Membership is free, and the site works well using the Midori web browser included in the Debian distribution for the Raspberry Pi. Page Introducing Python Python make it a valuable tool for anyone who wants to learn to program. It also makes it easy to spot so-called syntax errors caused by for- getting to put an end-quote in a command or forgetting to comment out a remark.

When a comment is found, Python ignores it and skips to the next line. The while loop, however, uses two. Next, set up a new pygame fpsClock display surface—the canvas onto which in-game objects will be drawn—with the following two lines The last line, pygame. Downloading the source code from the website will save you Page As usual, create a new project in IDLE or a text editor and enter the shebang line along with a comment describing the purpose of the program:! Page Chapter Har d ware Hackin g At the most basic level, a keyboard is little more than a col- lection of push-buttons.

Page Reading Resistor Colour Codes. Thankfully, the resistor colour codes follow a logical pattern. Figure shows a typical four- band resistor. A high-resolution colour version of this diagram is available on the Raspberry Pi User Guide website at. Page Sourcing Components. The spacing of these headers is particularly important: 2. Page Uart Serial Bus 3. Page RPi. If you want to check your circuit immediately, move the wire from Pin 11 to Pin 1 to make the LED light up.

If you were controlling additional devices, you could add more lines GPIO. Most Raspberry Pi Linux distri- butions restrict the use of the GPIO port to the root user, so the program will need to be run using the command at the terminal to get it started.

This is a pull-up resistor, and will provide the Pi with a reference voltage so it knows when the button has been pressed. This provides the 3. When the push-button is pressed, the circuit is grounded and becomes low, providing the cue for your Python program to know that the button has been activated. You can also combine both input and output examples into a single program, which waits for the button to be pushed and then turns on the LED by sending the output pin high.

Page This, among other reasons, is why the Raspberry Pi itself is built on a printed circuit board PCB rather than a breadboard—although the breadboard method was certainly used in the early days of prototyping the device.

Page A Brief Guide To Soldering Soldering works by melting a small quantity of metal to form a join between two compo- nents.

Also make sure the area is well ventilated. Some add-on boards for the Raspberry Pi are also provided in kit form and require soldering, including the Slice of Pi from Ciseco. Table provides a An add-on board with the same footprint as the target device, designed to connect to on-board headers and sit above the surface of the original board is a common sight in the Arduino world, where such add-on boards are known as shields. The Gertboard is almost two-and-a-half times larger than the Raspberry Pi itself, mak- ing it both the most powerful and the largest add-on board for the Pi available at the time of writing.

Page The Gertboard connected to a Raspberry Pi Perhaps the most important feature of the Gertboard is the protection it offers to the Pi.
