Raspberry Pi with Java (JJUG)
The document discusses various projects and resources related to using Java with Raspberry Pi, including how to find USB scales and print weight data. It covers a line-following robot called 'Mr. Grabby' and provides an algorithm for its operation, along with links to related code and hardware resources. Additionally, it mentions Java constructive geometry for creating and visualizing geometries for 3D printing.
