Experience
Open Liberty Space Sentry
https://github.com/fwji/liberty-sentry-challengeMoreover, the idea behind the game is to have different technologies working together with the addition of Legos that helped to reach out to audiences and developers of diverse technical backgrounds. We decided to open-source the entire project starting this year, so it can reach out to more people who want to learn Java and microservices using a different approach. We'll document every bit required to run the project, including Lego assembly instructions, Arduino codes, and, most importantly, Java microservices code.
