A Perfect Match: Java and the Internet of Things

Here's the opening paragraph from the new OTN article "A Perfect Match: Java and the Internet of Things:"

Maker Faire Booth

"The recent MakerCon Conference, hosted by Oracle, along with the 2014 Maker Faire, made it clear that the Maker Movement—a vital source of hardware innovation—is catching fire and opening up rich possibilities for Java developers. The match between the Maker Movement's ingenious intelligent devices and embedded software technology is central to the development of the connected world, the Internet of Things (IoT), and machine-to-machine (M2M) technology. As embedded devices get cheaper, more powerful, and more connected, and as the Internet of Things grows, Java developers are receiving strong support from Oracle as they face radical new challenges and opportunities. Java is best equipped to serve as a unified standardized platform for the Internet of Things. To that end, a major effort to unify the Java platform is underway—specifically, Java ME with Java SE—to shrink Java SE into the embedded space and smaller devices."

Challenge Ends on Friday!

This is your last chance to win a JavaOne trip. Submit a project video and code for the IoT Developer Challenge by this Friday, May 30.  12 JavaOne trips will be awarded to 3 professional teams and one student team. Members of two student teams will win laptops and certification training vouchers.


Ask your last minute questions on the coaching form or the Challenge forum. They will be answered promptly. Your project video should explain how your project works. Any common video format such as mp4, avi, mov is fine.


Your project must use Java Embedded - whether it is Java SE Embedded or ME Embedded - with the hardware of your choice, including any devices, boards and IoT technology. The project will be judged based on the project implementation, innovation and business usefulness. More details on the IoT Developer Challenge website 


Just for fun! Here is a video of Vinicius Senger giving a tour of his home lab, and showing his boards and gadgets.

Source Code for IoT Developer Challenge Projects

Discover source code that can help you create a project for IoT Developer Challenge. These code samples are open source, available on Github and may be reused in your own project. 

Check out the Pi4J code to create a command from Twitter, to connect a camera, or sensors using I2C or any GPIO Raspberry Pi pins. Pi4J project is intended to provide a bridge between the native libraries and Java for full access to the Raspberry Pi.


You may want to create an interface for your project using JavaFX. There are simple steps to build a JavaFX interface.


Ask your questions on the forums and using the coaching form. Remember the deadline is in a week on May 30

IoT Developer Challenge Hangouts!

The last two Hangouts with our Coach Vinicius Senger are taking place tomorrow Thursday: 
  • A Hangout in Portuguese at 4:00pm California time or 8:00pm Brazilian Time 
  • Hangout in English at 6:00pm California time, 9:00pm Eastern time, 10:00pm in Brazil. The same session will happen on Friday at 9:00am in Singapore, 10:00am in Tokyo Japan, 8:00am in Jakarta Indonesia 
Vinicius will present his lab, tools, CNC machine and many devices that he created like robots, wifi camera, panels, home automation and more! Join us and learn about the many possibilities to use Java Embedded, different types of single-board computers and your creativity.

Ask your questions at the end of these Hangouts, on the Challenge forum or using our coaching form. We are making more code available to help with your projects. Check the code samples page on IoT Developer Challenge website.

IoT Developer Challenge Countdown

Things are heating up with less than 10 days left to submit a project video and the code for IoT Developer Challenge by the May 30 deadline. Don't miss this chance to win a trip to JavaOne for up to three members of your team!  Use the video to show how the project works.

There is still time to get your questions answered on the forums or by filling out the coaching form. We are monitoring both and your questions will be answered promptly.  

Project complexity is less important than completeness of concept. Mostly your project should work without requiring additional development. In the implementation, we look at whether you use Oracle Java Embedded - and you may use other languages or frameworks, of course. Real world implementation, a.k.a 'Utility of Entry', is only 25% of the judging criteria. Visit the the Challenge website for more details. 

The judges will score the Entries based on the following criteria:
