To reiterate my idea:
Sound exists as sound wave but is only perceived by us through vibration of objects. In this project, I want to change the way we perceive and manipulate sound by emphasizing on the motion of sound waves.
As a violinist, I feel the music through the position of my fingers. When I first learned how to find the right finger positions to play different notes, my perception of pitch carries a more physical form (location on finger board). I am inspired by this idea and want to present that experience through this project.
As the user move their hand across the strings, the tensity/deformation of strings varies. The users will then fine tune the instrument by finding the pattern of pitch change with respect to their finger position. The sound is really unstable, which adds emotion and interaction to this instrument.
More problems I ran into/Things I fixed:
1. The IR sensor reading was really unstable. I first changed how often I take the data but the reading still fluctuate a lot. So I googled and found that I should add a 100 uF capacitor.
2. Servo almost did not work. After I fixed the IR reading and sound input, I could not start my servo. I played around with the range of servo input and double checked the wiring, and I did not find any error. Then I increased the current and voltage input and suddenly the servo was running. (the arduino god did not give up on me!!)
