CapacitiveBoard (CapBoard) is a capacitive sensing prototyping board based on Arduino Nano. CapBoard allows to transform any conductive object in a capacitive sensor able to detect the touch of a person.
The board makes it possible to connect up to nine different conductive objects; also, it has eight analog inputs that can be used to connect potentiometers or other types of sensors.
If connected to a laptop, the board sends the data relating the state of the sensors via the serial connection. Currently CapBoard has been interfaced with Pure Data, Max/MSP and Processing.
By programming CapBoard you can create 8-bit standalone DIY synths controlled by sensors and knobs or by touching the objects connected to it. The board is equipped with a LED connected to the digital port number 13, while port 9 is free and can be used to connect a speaker or an audio cable to generate sounds through the Arduino tone() function or using the Mozzi sonification library for Arduino.
