Overview of this book

Android Things makes developing connected embedded devices easy by providing the same Android development tools, best-in-class Android framework, and Google APIs that make developers successful on mobile. With this book, you will be able to take advantage of the new Android framework APIs to securely build projects using low-level components such as sensors, resistors, capacitors, and display controllers. This book will teach you all you need to know about working with Android Things through practical projects based on home automation, robotics, IoT, and so on. We’ll teach you to make the most of the Android Things and build enticing projects such as a smart greenhouse that controls the climate and environment automatically. You’ll also create an alarm system, integrate Android Things with IoT cloud platforms, and more. By the end of this book, you will know everything about Android Things, and you’ll have built some very cool projects using the latest technology that is driving the adoption of IoT. You will also have primed your mindset so that you can use your knowledge for profitable, practical projects.

Chapter 7. Build a Spying Eye

In this chapter, we will build a spying eye. In more detail, we will build a project that uses an Android Things board to control a camera and a servomotor that we will use to rotate the camera. Through this project, we will learn how to use PWM pins. The Pulse Width Modulation (PWM) pin is a different kind of pin that we will use to control different types of peripherals such as servo motors. In more details, in this chapter we will explore:

  • How to use PWM pins in Android Things
  • How to control servo motors
  • How to use cameras

At the end of this chapter, we will build a fully working Android Things system that is able to acquire images using the camera and, at the same time, we will be able to control the camera direction using a servo motor.
