4x peizo sensors + breakout boards

1x arduino - preferably leonardo

1x pair slippers

4x wire connectors to make life easier4

install peizo sensors into the rubber portion making slits to slide the sensors into, connect it up. (make sure to pick a nice spot where the shoes do not bend much.

connect the midi inputs to the analog pins of the arduino.

on arduino leonardo you can create a usb interface to send messages as a device, otherwise console feedback can be used.
