Abstract: This project demonstrates the construction of an automated xylophone using recycled glass bottles as teaching aids in Natural Sciences courses. This instrument seeks to integrate music and technology to teach electronics, programming, and music concepts, fostering creativity and critical thinking. The use of recycled glass bottles gives the project a sustainable and environmentally aware approach, as well as developing collaborative skills. The automated xylophone allows students to explore physical concepts such as frequency, amplitude, and time, as well as mathematical concepts such as proportionality, in a practical and fun way. The project employs the Helmholtz resonator principle, in which the volume of air in a bottle and the neck act as a mass-spring system to determine the resonance frequency of the sound produced. The resonance frequency is adjusted based on the volume of water in the bottles, which alters the height of the internal air columns. The methodology is based on mechanical construction using DC motors and 3D-printed drumsticks, as well as an electronic system implemented through Arduino. Arduino programming automates the playback of melodies and fine-tunes their sound parameters. An Android app was developed to control the system via Bluetooth and was designed to play default songs from a catalog and create melodies. The results show that the project successfully created an educational experience with an interdisciplinary focus, focusing on science, technology, engineering, art, and mathematics (STEAM). The project received awards at the regional and state levels in Rondônia, receiving a merit and innovation award. In the future, plans include increasing the number of bottles to include semitones and using motion sensors to automatically trigger the notes.
