Key FeaturesExplore the small yet powerful mini computer in order to run java applicationsLeverage Java libraries to build exciting projects on home automation, IoT, and Robotics by leveraging Java librariesGet acquainted with connecting electronic sensors to your Raspberry Pi 3 using Java APIs.Book DescriptionRaspberry Pi is a small, low cost and yet very powerful development platform. It is used to interact with attached electronics by the use of its 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 Pis 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 adafruit.io. 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.What you will learnUse presence detection using the integrated bluetooth chipAutomatic light switch using presence detectionUse a centralized IoT service to publish data using RPCControl a robot by driving motors using PWMCreate a small web service capable of performing actions on the Raspberry Pi and supply readingsImage capture using Java together with the OpenCV frameworkAbout the AuthorPradeeka Seneviratne is a software engineer with over 10 years of experience in computer programming and systems designing.
