Idea
Create melodies from falling leaves and generate sounds instantly.
Plan
1. Draw a music sheet near the tree.
2. The leaves from tree fall on the staff. (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.
Process * Test how sensitive the ultrasonic sensor is to detect an object
recipe : The size of the circle changes according to the value of the ultrasonic sensor.
