Bit-Tree Creativity - Ultrasonic Ranging Air Piano

Hexagonal Interactive Tech Device (Ultrasonic Ranging Air Piano)

This air piano adopts an ultrasonic module to detect hand distance in real time. The main controller maps different distances to corresponding musical notes and drives a buzzer to play various tones. Equipped with an OLED screen that synchronously displays the detected distance and matched notes, it enables contactless performance without physical keys.

Contact-free playing without keys; non-contact design is more hygienic.

High-precision ultrasonic ranging; tone changes with distance.

Real-time OLED display, suitable for both popular science demonstration and teaching.

BIT-TREE CREATIVITY

STEAM skills like programming will be a core competency for the next generation, and the time to cultivate this ability is now.
