Abstract :
HSRvote is a teaching tool that allows teachers to visualize the progress of their students. It brings the prickle and the glamour of a quiz show into the classroom. Tests are becoming a game and the fun factor is guaranteed. The devices for the students contain a battery-driven CC2530 (uC with RF frontend) and four push-buttons for the answer options. On pressing the push-button, a short 802.15.4 radio telegram of less than a millisecond is delivered to the RF receiver sitting in a USB dongle on the teachers PC.
