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:
