Picture of an Arduino

Here is a picture of an Arduino, I am not sure what version.

This particular Arduino is running a Theremin, which is an early type of electronic musical instrument - when I was a boy in the 1960s, the scary theme tune for Doctor Who (in black and white) was played on a Theremin.

Here is a link to the site providing the picture:
