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.

Introduction


In the previous chapter, we made use of the Raspberry Pi GPIO to directly control and respond to the attached hardware by controlling or reading the GPIO pins. In this chapter, we will learn how to collect analog data from the real world and process it so we can display, log, graph, and share the data and make use of it in our programs.

We will extend the capabilities of the Raspberry Pi by interfacing with Analog-to-Digital Converters (ADCs), LCD alphanumeric displays, and digital port expanders using Raspberry Pi's GPIO connections.
