Persistence of Vision, v1.0

Documenting the first successful test using the idea of persistence of vision and my own LED circuit. Shown below is an ATMega8 microcontroller connected to 8 LEDs through 8-100 Ohm resistors. Flickering the LEDs in a certain order at a certain rate while being moved creates the illusion of text being written.
