The CALEIDUINO is an Arduino-based digital and sound reactive kaleidoscope, designed to serve as a toy, an art object, and a tool for teaching electronics and programming in a playful yet creative way.
At the heart of CALEIDUINO is a PCB for connecting an Arduino Nano, a TFT 1.8 “display, an analog 3-axis accelerometer GY-61, a piezoelectric, a switch, and a 9V battery–all of which are housed inside a hexagonal methacrylate case. Just like in any kaleidoscope, t three mirrors in triangular prism shape, while an accelerometer collects a user’s movement to generate the psychedelic graphics and sounds.
In terms of software, the CALEIDUINO uses the Arduino IDE along with the Adafruit GFX and ST7735 libraries. The project is entirely open source and is the work of artist José Manuel González. You can read more about the device here, or see it in action below.
