Finally got something working!

My waveshield was not working at all, so I am now trying piezo speakers. I set them up to be like a flex sensor, where they buzz when pushed. To fit my original idea, however, I want to make a wearable device that makes sound when I walk around. Therefore I will need to place the piezos on my arms and legs. My only problems right now are that the speakers are extremely quiet and take a lot of force to hear.
