Carlo has put his Arduino microcontroller to work as a POV device. Anyone interested in making their own can download the sample code that he is providing.
“This is my first attempt to create a persistence of vision (POV) display using the Arduino. The ultimate goal is to mount it on my bike wheel and have it display nice things while I ride. But, for now, it consist of an array of 6 LEDs mounted on a turning rig I made From scrap material. The LEDs are directly connected to the pins 2 to 7 of the Arduino and their current is limited by the resistors. The entire circuit is powered by the 9V battery.”
