This board is designed to be integrated with the Bare Conductive Paint, though you can use many other conductive tools (it has 12 electrodes which can have any conductive material connected to it). But if you can paint your own, why would you use anything else?

The pre-programmed Touch Board is Arduino-at-Heart, so your Arduino shields and code will work seemlessly with it as if it were an Arduino Leonardo. It can also play music off an SD card — you could even paint a piano and turn your Touch Board into a synthesizer! Take advantage of it’s LiPo battery charger you can make any of your projects mobile.
