Bare Conductive Touch Board
PRODUCT ID: SKU-5013
Turn touch into sound, light, or data
Straight out of the box, the Touch Board is pre-programmed to turn any conductive object into a sensor or switch to play sounds stored on the included microSD card. It can be re-programmed via the Arduino IDE so you can customize the function of the 12 capacitive touch and proximity sensors.
Create smart surfaces by connecting pads of Electric Paint or other conductive materials to your Touch Board. Use the Touch Board to bring your ideas to life. Create interactive murals, sophisticated prototypes or playful projects.
12 capacitive touch and proximity electrodes.
Completely Level Base
Easily attach it onto any flat surface.
MP3 decoder and MIDI synthesizer
Play MP3 files or simulate a MIDI instrument via speakers or headphones connected to the audio jack.
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.
