Arduino-tan, the Object-tan of the Arduino Uno microcontroller board! What is Object-tan? It's the name given to an "moe anthropomorphized" object, in this case the Arduino. There have been many Object-tans already created, as its a fairly common occurrence in the otaku culture to make something look cute. There are OS-tans, a Wiki-tan, console-tans, and so much more...
Above: Arduino-tan! Arduino-chan? Arduina-chan?
Arduino Uno-chan? Arduino Una-chan? ..tan?
Pretty much anything can be moe-anthropomorphized. Food, military vehicles, animals, laws, household appliances, buildings - nothing is safe from the cuteness! D:
