Touch Board can turn almost any material or surface into a sensor by connecting it to one of its 12 electrodes, using conductive paint or anything conductive.
Touch Board is a tool to make your projects interactive, responsive, smart or just fun. It’s designed as an easy-to-use platform for a huge range of projects, whether it's painting alight-switch on your wall, making a paper piano or something nobody's thought of yet.
