I/O Coincidence Lab: Musical Flower Vase

For this project I created a vase that changes the song it plays depending the level of water contained inside. The water level is detected by the fsr placed beneath the vase. The basic pattern remains the same, but the notes change, as the water level increases or decreases. Dropping glass stones or pouring more water into the vase allows a user to change up the music. An LED illuminates the vase and pulses with the music. 
 
Possible Uses: This vase could be used as a type of ambient media in a couple of use case. A variation of this vase could be made, with a small change to the code, such that the music plays only when the input to the fsr drops below a certain threshold, signaling that the water in the flower vase is low and needs to be replenished. When the buzzer is disconnected, the vase makes a nice nightlight, and the addition of a photocell could enable it to turn on only if the light level is very low.
 
I reused the music code from PlayMelody, as I am terribly untalented when it comes to making music.
