Raspberry Pi 3 Cookbook for Python Programmers - Third Edition

By: Steven Lawrence Fernandes, Tim Cox

Overview of this book

Raspberry Pi 3 Cookbook for Python Programmers – Third Edition begins by guiding you through setting up Raspberry Pi 3, performing tasks using Python 3.6, and introducing the first steps to interface with electronics. As you work through each chapter, you will build your skills and apply them as you progress. You will learn how to build text classifiers, predict sentiments in words, develop applications using the popular Tkinter library, and create games by controlling graphics on your screen. You will harness the power of a built in graphics processor using Pi3D to generate your own high-quality 3D graphics and environments. You will understand how to connect Raspberry Pi’s hardware pins directly to control electronics, from switching on LEDs and responding to push buttons to driving motors and servos. Get to grips with monitoring sensors to gather real-life data, using it to control other devices, and viewing the results over the internet. You will apply what you have learned by creating your own Pi-Rover or Pi-Hexipod robots. You will also learn about sentiment analysis, face recognition techniques, and building neural network modules for optical character recognition. Finally, you will learn to build movie recommendations system on Raspberry Pi 3.

Introduction


One of the key aspects of Raspberry Pi that differentiates it from an average computer is its ability to interface with and control hardware. In this chapter, we use Raspberry Pi to control remotely activated mains sockets, send commands over serial connections from another computer, and control the GPIO remotely. We make use of SPI (another useful protocol) to drive an 8 x 8 LED matrix display.

We also use a Bluetooth module to connect with a smartphone, allowing information to be transferred wirelessly between devices. Finally, we take control of USB devices by tapping into the commands sent over USB.
