An experimentation with peizo electric using arduino resulted into a musical instrument. which has the shape of a mushroom and it produces psychedelic like sound.
The project was done together with Matin Lukac (one of the finest man I have met).
We gave it a fungus flower like shape,in which each flower is attached to a common base made up of acrylic, which houses the Arduino and the bread board. Each fungus ends with an inverted aluminum cup, which not only gives it a flower like look but it is also acts as an amplifier and conceals the piezos.
WE made use of an arduino example. and modifies it according to our liking. here is the example.
