The Touch Board adds touch and proximity sensing to your interactive project. It features a microcontroller board with 12 capacitive touch and proximity electrodes, so each electrode can be used to trigger a different sound and can be used to turn any material or surface into a sensor.

The Touch Board is a microcontroller board based on the Arduino Leonardo and uses the ATmega32U4, running at 16MHz and 5V.

Great little product

If you want to make noises or play with capacitive touch this is the way to go.

Simple to Use, Great Documentation and Resources

Currently using this on an interactive installation art project. For the ease of use and lack of headache in getting it up and running, it's definitely worth the money! The website also has great examples, libraries, and documentation of different ways of using the board. I'm using it in conjunction with other software so what I'm about to say isn't a problem for me, but a note to those who may want to use it as a standalone capacitive sensor MP3 board (i.e., how it's set up out of the box), it appears to only reliably trigger one sample at a time (monophonic). I'm sure you could tweak the code and make it polyphonic however!
