Raspberry Pi 3 Projects for Java Programmers

By: Rajdeep Chandra, John Sirach, Pradeeka Seneviratne

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 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.

A Social and Personal Digital Photo Frame

The Raspberry Pi is a great single-board computer for working with multimedia projects, that is, the integration of graphics, audio, video, and so forth. This chapter presents how to make a social and personal digital photo frame using the Raspberry Pi 3 with a few hardware and software components. It can be mounted on a desktop or attached to a wall, like a traditional photo frame.

The social media platform we'll be going to use is Flickr, which provides a Flickr API to deal with a set of Flickr web services. The photo frame is capable of fetching all the images stored in a specified Flickr album and displaying them as a full-screen slideshow on a video display at regular intervals. Also, the photo frame can periodically sync its local image library with the pointed Flickr album.

In this chapter, we will cover the following topics:
