Drawing Board
It was not hard to connect the circuit and modify the code, since I had experience using them in previous classes. However, I construed the instruction as making a circle that moves, instead of making a drawing brush, which lead to the following video.
After consulting with one of the fellows, I realized that I should’ve made a brush that leaves continuous traces on the screen. So I modified the code: delete the “background(0)” from void draw section, and then made the circle smaller, which lead to the following outcome.
The traces that the circle leaves is not continuous enough. I think that is because the rate at which the potentiometer sends signal exceeds the the frame rate.

My midterm project was mainly about buzzers so it did not take me much time to figure out how a buzzer works. However, I couldn’t figure out how the duration works here. I expected to work even without duration. But as I deleted the duration function, it immediately stopped working.
