IntroductionIntroduction
Traditionally, while we are playing music, we must stop from time to time to turn over to the next page
Therefore we come up with an idea of making an automatic score flipper.

Problem 1: Can the score be flipped in the opposite direction?
Answer: Another set of flipping component with a reverse circuit can be added to our production.

Problem 2: Will the noise made by the product disturb the user while playing?
Answer: To solve this problem, we covered the motor by pieces of plastic. The noise produced is minimized.

Problem 3: Will the production crimple the score while the belt moves?
Answer: The speed of the motor will be adjusted so it will not crimple the paper.
