Overview of this book

Raspberry Pi is a small, low cost and yet very powerful development platform. It is used to interact with attached electronics by the use of it's GPIO pins for multiple use cases, mainly Home Automation and Robotics. Our book is a project-based guide that will show you how to utilize the Raspberry Pi's GPIO with Java and how you can leverage this utilization with your knowledge of Java. You will start with installing and setting up the necessary hardware to create a seamless development platform. You will then straightaway start by building a project that will utilize light for presence detection. Next, you will program the application, capable of handling real time data using MQTT and utilize RPC to publish data to Further, you will build a wireless robot on top of the zuma chassis with the Raspberry Pi as the main controller. Lastly, you will end the book with advanced projects that will help you to create a multi-purpose IoT controller along with building a security camera that will perform image capture and recognize faces with the help of notifications. By the end of the book, you will be able to build your own real world usable projects not limited to Home Automation, IoT and/or Robotics utilizing logic, user and web interfaces.

Starting our project and installing the necessary libraries

This project is available for download and can be opened within NetBeans. The only thing we need to do is change the project's properties so it is able to be run on the Raspberry Pi. When the project is opened, go to the project's Properties and by selecting the Run node on the left side, we can change the Runtime Platform to the Raspberry Pi platform. This is explained in detail in Chapter 1, Setting up Your Raspberry Pi, in the Our First Remote Java Application section.

For our project, we need a couple of libraries. We will be using the libraries from the Pi4J project that enable us to interact with the Raspberry Pi pins and use BlueCove libraries to be able to interact with the Bluetooth chip.

Although the libraries are available in the project, it will be useful to know how these are added to the project if you start afresh. This will be...
