Touch Board

Turn touch into sound, light, or data. Create smart surfaces by connecting pads of Electric Paint or other conductive materials to your Touch Board. Use the Touch Board  from Bare Conductive to bring your ideas to life. Create interactive murals, sophisticated prototypes or playful projects.

Features

• 12 CAPACITIVE ELECTRODES
  The Touch Board has 12 capacitive electrodes that respond to a touch. These electrodes can be extended with conductive materials, like Electric Paint,
• MP3 PLAYER AND MIDI SYNTHESIZER
  The Touch Board has on-board MP3 playback and a MIDI synthesizer. This means you can either play MP3 files or simulate a MIDI instrument by touching the electrodes.
• 3.5MM AUDIO SOCKET
  In order to hear the sounds coming from the Touch Board simply connect either headphones or speakers to the 3.5mm audio socket.
• MICROSD CARD READER
  Upload MP3 files onto the supplied microSD card and change it without having to reprogram the Touch Board.
• USB SERIAL, MIDI INTERFACE AND MOUSE AND  KEYBOARD
  When plugged into a computer, the Touch Board can act as a USB serial device, USB MIDI interface or as a USB mouse or keyboard. Use the data from the electrodes as an input for software that utilises either serial, MIDI or keyboard strokes.

The Touch Board is a microcontroller board with dedicated capacitive touch and MP3 decoder ICs. It has a headphone socket and micro SD card holder (for file storage), as well as having 12 capacitive touch electrodes. It is based around the ATmega32U4 and runs at 16MHz from 5V. It has a micro USB connector, a JST connector for an external lithium polymer (LiPo) cell, a power switch and a reset button.

It is similar to the Arduino Leonardo board and can be programmed using the Arduino IDE. The ATmega32U4 can appear to a connected computer as a mouse or a keyboard, (HID) serial port (CDC) or USB MIDI device.
