DIY POV Toy

In his post,  justDIY stated:

“Persistence of Vision is some sort of effect, either psychological or biological in nature, that allows our eyes and brain to ‘see’ motion and patterns in a sequence of rapidly stills (hence a movie projection). This effect can be exploited using basic digital electronics to create a virtual LED sign, which the viewer will ‘see’ when the pov toy is put in motion.”

You can build your own Persistence of Vision (POV) toy with the following materials:

  • Microchip PIC12F683 microcontroller,
  • a 74HC595 serial shift register
  • eight 3mm LEDs of different colors

The circuit schematic for the POV toy is seen here. For other details on the circuit operation and design steps refer to justDIY’s design of POV toy.
