Touch Board Starter Kit

Touch Board Starter Kit: one board, a little bit of paint, an inexhaustible source of inventions

This electronics kit designed by Bare Conductive includes two main components: the Touch Board programming board (sold separately on our website) and Electric Paint.

With the board, you can connect almost anything to capacitive electrodes or to the I/O pins of an MP3 decoder and transform your environment into a giant interactive project.

With the paint, you can draw all the circuits you can think of, on any support. The kit is accessible to beginners and seasoned hobbyists, as well as researchers, teachers and designers.

Bare Conductive Touch Board kit: a comprehensive kit to recreate your world

With the Arduino compatible programming board and the electric paint, Bare Conductive has included a multitude of accessories to foster creativity: a house stencil to paste on a wall, tabs and stickers, brushes, alligator clips for making your connections... Not forgetting a microSD card and its reader, a mini speaker, and some cutouts for easier painting.

This kit mixes arts and electronics projects expertly. And as you’ll see in the Resources section below, you’ll never fall short of ideas!
