The EduBuzzer project includes everything from the application framework running on the teacher's workstation to the hardware of the EduBuzzer. All of it can be downloaded from our [[HSC2011/Download instructions|download area]]. | The EduBuzzer project includes everything from the application framework running on the teacher's workstation to the hardware of the EduBuzzer.

** 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#VM|virtual machine]]. | ** The [[HSC2011/Software#Firmware|firmware]] flashed on the EduBuzzers and the base station reacts on hardware events and commands received over radio.
