Raspberry Pi for Python Programmers Cookbook - Second Edition

Overview of this book

Raspberry Pi cookbook for Python Programmers is a practical guide for getting the most out of this little computer. This book begins by guiding you through setting up the Raspberry Pi, performing tasks using Python 3 and introduces the first steps to interface with electronics. As you work through each chapter you will build up your skills and knowledge and apply them as you progress throughout the book, delving further and further into the unique abilities and features of the Raspberry Pi. Later, you will learn how to automate tasks by accessing files, build applications using the popular Tkinter library and create games by controlling graphics on screen. You will harness the power of the built-in graphics processor by using Pi3D to generate your own high quality 3D graphics and environments. Connect directly to the Raspberry Pi’s hardware pins to control electronics from switching on LEDs and responding to push buttons right through to driving motors and servos. Learn how to monitor sensors to gather real life data and to use it to control other devices, and view the results over the Internet. Apply what you have learnt by creating your own Pi-Rover or Pi-Hexipod robots. Finally, we will explore using many of the purpose built add-ons available for the Raspberry Pi, as well as interfacing with common household devices in new ways.

Viewing data from your own webserver


Gathering and collecting information into databases is very helpful, but if it is locked inside a database or a file it isn't much use. However, if we allow the stored data to be viewed via a web page it will be far more accessible; not only can we view the data from other devices, we can also share it with others on the same network.

We shall create a local web server to query and display the captured SQLite data and allow it to be viewed through a PHP web interface. This will allow the data to be viewed, not only via the web browser on the Raspberry, Pi but also on other devices, such as cell phones or tablets, on the local network:

Data captured in the SQLite database displayed via a web-page

Using a web server to enter and display information is a powerful way to allow a wide range of users to interact with your projects. The following example demonstrates a web server setup that can be customized for a variety of uses.
