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.

You’ve got an Arduino

The Touch Board is easily programmed via the Arduino IDE. Use the tutorial below to get our libraries and example sketches on your machine instantly. Tune your distance sensors, play MP3s or make an amazing MIDI controller. It’s just an upload away.

Programming the Touch Board with Arduino

You’ve got an MP3 Player

Your Touch Board will arrive programmed as an MP3 player. Want to switch our audio guide for your favourite tunes? Just follow the straightforward tutorial below. Want to use the MP3 functionality for another project? Great. Our libraries make it easy to control your files.

Precautions of use:
Children under 14 years of age must be supervised by an adult whilst using this product. This board may be powered over USB, by an approved 3.7V Lithium Polymer cell or a 3.0~5.5V DC power supply. Observe battery polarity markings carefully before use. Do not use on conductive/met-­‐al surfaces as this may short circuit the board and damage it. Bare Conductive takes no for external circuitry connected to this board.
