Probably, you have seen many assorted rotating persistence of vision (POV) based LED displays, but this project is somewhat cool and different. Embedds member expressed his opinion on his build The Rotating LED POV Display as:
“Honestly, this rotating LED POV display is a little bit different than the others, as it’s one well constructed devicethat comes with very solid construction. Furthermore, it can display multiple colors at the same time.”
You can build such POV displays using MAX233 RS232 level converter, shift registers, Motor with three short M3 bolts, 16 double color (red+green) LED, a +12V dc source and a rotating board. You have to arrange all the LEDs in one straight line as shown in the picture.
