Buzzer with flex

Here is a video of the buzzer changing pitch with the flex sensor I was able to find the code and example online here are the links i used  http://fritzing.org/projects/piezo-flex-sensor-simple#c675

and  http://fritzing.org/media/fritzing-repo/projects/p/piezo-flex-sensor-simple/code/flexiePiezoPFollow.ino

I was able to change the pitch and will still work with it and see what else I can do.
