Bare Conductive Touch Board

The Touch Board makes your projects interactive.

One tool, a million possibilities! Create sensors with the Touch Board’s 12 electrodes and trigger sounds through its MP3 player. Make a MIDI piano, an interactive wall, a proximity sensor — you decide. Use our cross‐platform  installer to add loads of code examples to the Arduino IDE.

Not sure where to get started? Take a look at our Touch Board Starter Kit. It comes  with all the materials and ideas you need to get making today!

Works with:
Protoshields, crocodile clips,  copper tape, solder and e‐textiles. Use with Electric Paint to design your own sensors.

LEVEL: Beginner to Expert Engineer

Getting started is easy

The Touch Board comes pre-programmed with an audio guide that takes you through basic features and highlights of the board. This tutorial below will get you up and running in no time.

Getting Started with the Touch Board

Capacitive touch and distance sensing

Want to paint an interactive wall? The Touch Board is for you. Connect something conductive – like our Electric Paint – to any one of the 12 electrodes and turn it into a reliable touch or distance sensor. Use the tutorials below to see the power of the Touch Board’s sensors in action.
