Create melodies from falling leaves and generate sounds instantly.


1. Draw a music sheet near the tree.

2. The leaves from tree fall on the music sheet. (The leaves become one note)

3. The ultrasonic sensor measures the location where the leaves have fallen (the distance between the ultrasonic sensor and the leaves).

4. Through coding, the speaker produces different sounds (the note where the leave on the music sheet) depending on the distance.
