Bit-Tree Creativity - Music Creation Interactive Device

Hexagonal Interactive Tech Device (Music Creation Interactive Device)

This 16-key touch piano uses a touch sensing module to detect key signals. The main controller maps 16 touch points to different musical scales. When triggered, it drives the buzzer to play the corresponding tone. Meanwhile, the OLED screen synchronously displays the currently played note in real time, providing clear and intuitive feedback.
