Bare Conductive Touch Board

SKU SS-109990039


The touch board is a tool to make your projects interactive, responsive, smart or just fun. Use the Touch Board to change the world around you by turning almost any material or surface into a sensor. Paint a lightswitch on you wall, make a paper piano or create something nobody’s thought of yet.

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.

The Touch Board uses Atmel’s ATMega32U4 Microprocessor to make the board easy to use, flexible and widely accessible. Built in USB hardware lets the Touch Board perform a variety of functions.
