Persistence of Vision (POV) with 5 LEDs

// a project by Glen p yeldho

// http://www.instructables.com/id/Simple-Arduino-POV-/
// Edited by GreenMoonArt to spell "TECH_"
// Connect 5 LEDs to Arduino digital pins 2, 3, 4, 5, and 6 via 200 Ohm resistors
// Upload the code and shake the breadboard with the LEDs on it. 
// Vary the shaking frequency until you can see text formed by the LEDs.
