The project shows how to setup a Web application to control RGB LED panels from Raspberry Pi. The Webapp uses an Adafruit RGB LED Matrix HAT and the rpi-rgb-led-matrix C++ library to drive the panels. The Web application is implemented using Java EE.

Press Your Button is a single or multi-player game written for Raspberry Pi. It uses a button, attached to a GPIO pin, to tell the computer when to stop the score board. Players take turns until one reaches the target score.

The Raspberry Pi's GPIO pins are used to play RTTTL sequences on a piezo buzzer. It is Web enabled and Java-powered. The Web app has built in RTTTL tones, as well as input controls for playing user provided RTTTL tones.

Using built the built-in JVM, the Raspberry Pi hosts Web enabled controls for the PIXEL. The PIXEL is an LED matrix driven by a IOIO derivative. Much like the desktop and mobile applications for PIXEL, this version features scrolling text, still images, and GIF animations.
