Bare Conductive Touch Board

The Touch Board is designed as an easy-to-use platform for a huge range of projects. Use the Touch Board to change the world around you by turning almost any material or surface into a sensor. Paint a lightswitch on your wall, make a paper piano or create a custom interactive surface. Connect anything conductive to one of its 12 electrodes and trigger a sound via its onboard MP3 player, play a MIDI note or do anything else that you might do with an Arduino or Arduino-compatible device.
