Overview of this book

This Learning Path takes you on a journey in the world of robotics and teaches you all that you can achieve with Raspberry Pi and Python. It teaches you to harness the power of Python with the Raspberry Pi 3 and the Raspberry Pi zero to build superlative automation systems that can transform your business. You will learn to create text classifiers, predict sentiment in words, and develop applications with the Tkinter library. Things will get more interesting when you build a human face detection and recognition system and a home automation system in Python, where different appliances are controlled using the Raspberry Pi. With such diverse robotics projects, you'll grasp the basics of robotics and its functions, and understand the integration of robotics with the IoT environment. By the end of this Learning Path, you will have covered everything from configuring a robotic controller, to creating a self-driven robotic vehicle using Python. • Raspberry Pi 3 Cookbook for Python Programmers - Third Edition by Tim Cox, Dr. Steven Lawrence Fernandes • Python Programming with Raspberry Pi by Sai Yamanoor, Srihari Yamanoor • Python Robotics Projects by Prof. Diwakar Vaish

Working with solenoids


What we are going to make is an automation system that will water your plants whenever they need it. So technically, once it is set up, you don't really have to worry ever about watering your green creatures. Whether you are at your home, at the office, or on a vacation, this will keep doing its job no matter what. 

Now, you must be wondering how it will water the plants, so let me tell you, for every problem in this world, there exists a solution. In our case, that solution is called a solenoid valve. What it essentially does is switch the flow of liquids. There are various solenoid valves available in the market; some of the identifying features are as follows:

  • Size: They come in various sizes such as half an inch, three quarters of an inch, 1 inch, and so on. This basically will determine the flow rate of the solenoid valve.
  • Medium: Whether it is meant for fluid, gas, vapor, and so on.
  • Normal condition:
    • Normally opened: This valve will allow the flow of liquids in...
