Interfacing LED: Chasing LED (LED chaser)

 CHASING LEDs                   

In this project  8 LEDS are connected to PORTC of PIC 18F452 microcontroller and
the microcontroller is operated from a 4MHz resonator. The program turns on the
LEDs in a sequencial manner with a 1 second delay between each input. The net
result is that the LEDs seems to be chasing each other.
