Python Programming with Raspberry Pi

By: Sai Yamanoor, Srihari Yamanoor

Overview of this book

Raspberry Pi Zero is a super-small and super-affordable product from Raspberry Pi that is packed with a plethora of features and has grabbed the notice of programmers, especially those who use Python. This step-by-step guide will get you developing practical applications in Python using a Raspberry Pi Zero. It will become a valuable resource as you learn the essential details of interfacing sensors and actuators to a Raspberry Pi, as well as acquiring and displaying data. You will get started by writing a Python program that blinks an LED at 1-second intervals. Then you will learn to write simple logic to execute tasks based upon sensor data (for example, to control a motor) and retrieve data from the web (such as to check e-mails to provide a visual alert). Finally, you will learn to build a home automation system with Python where different appliances are controlled using the Raspberry Pi. The examples discussed in each chapter of this book culminate in a project that help improve the quality of people’s lives.

Preface

Components of the robot


Let's discuss the components of the robot using the labeled picture as an aid (shown in the following figure):

Components of the robot

The following is an explanation for the components of the robot:

  • The Raspberry Pi Zero controls the movement of the robot using a motor driver circuit (stacked on top of the Raspberry Pi Zero)
  • The motors of the robot are connected to the motor driver circuit
  • A USB battery pack is used to power the Raspberry Pi Zero. A separate AA battery pack is used to drive the motors
  • The robot is also equipped with a camera module that helps with driving the robot

We have included a suggested list of components where we chose the cheapest source available for the component. You are welcome to substitute with your own components. For example, you can use a webcam instead of using the Raspberry Pi camera module:
