In class, a group of four girls worked on Arduino Board. We had to make Sine Waves. We had to make the sine waves go from 0 to 180 degrees. To make the amplitude higher, we added a number in front of the sine equation. This makes the sound a higher pitch. Next, we had to change the number we divided the equation. The higher the number the faster the sound and lower the number the slower the sound is. If you click on the following link, and you can listen to the sound we made.
