Mari Kubota- Project 10- Sonic Sketch

For this project I used my project 3 code as a starting point. The movement in the x coordinate changes the frequency. The movement of the y coordinate changes the amplitude. Mouse press resets the frequency to a certain point. Pressing any key randomizes the frequency. If the firefly is off canvas, the sound automatically stops to prevent from any unsavory sounds.
