The EduBuzzer is a device designed to provide an additional channel of communication between students and teachers. It is a handheld box with four buttons that is in contact with the teacher's laptop or presentation station, from where he can initiate different modes (called "games") like voting, electronic raising of hands or team assignments. The devices themselves are generic enough that additional games can be implemented easily in JavaScript. | The EduBuzzer is a device designed to provide an additional channel of communication between students and teachers.

** The [[HSC2011/Software/Firmware|firmware]] flashed on the EduBuzzers and the base station reacts on hardware events and commands received over radio. If a game requires more complex actions on the hardware like animations over the LEDs, LED fading or music to be played, the firmware can run custom code in a [[HSC2011/Software/embedVM|virtual machine]]. | ** The [[HSC2011/Software/Firmware|firmware]] flashed on the EduBuzzers and the base station reacts on hardware events and commands received over radio.
