"Conducting the Future: The Rise of the Electronic Orchestra Baton"
Two students, Larry Lu and Kathryn Zhang, have developed an electronic orchestra baton that allows users to conduct music at home. The baton uses a Pico W and an IMU to detect the conducting speed and transmits this data to another Pico W, which then plays audio files at the corresponding tempo. The system also features a visualizer that pauses when the baton is set down. This innovation uses DMA and SPI communication to control audio output and visualizations, adjusting the playback speed by manipulating the DMA audio channel timer.
