CALEIDUINO is a sound interactive digital kaleidoscope based on Arduino. CALEIDUINO is a game, an object of art/artistic object and a tool to understand electronics and programming in a creative and entertaining way. The heart of CALEIDUINO is a PCB board that connects to an Arduino nano 3.0, a 1.8’ TFT screen, an analogic accelerator with three axis GY-61, a piezoelectric, a switch and a 9V battery. Just as with any kaleidoscope, three mirrors in the form of a triangular prism are used. The external part of the object is made of methacrylate. The idea is, as with analogical kaleidoscopes, to use the movement of the user (by means of the accelerator) to generate graphics and sound.
