Seconds Counter
Version 1 - Last update: Oct 17, 2015

Counts the seconds from 0 to 999.

All pins from "a" to "g" and pin "dp" of the displays are connected together. Each one is controlled by an Arduino's pin:

a = pin 2; b = pin 3; c = pin 4; d = pin 5;

e = pin 6; f = pin 7; g = pin 8; dp = pin 9.

The Groun Supplement (com1 and com2) is controlled separately by the pins:

Display 1 = pin 10

Display 2 = pin 11

Display 3 = pin 12

The technic is to turn one display on and turn the others two off for a shor period of time (5ms for each segment == 15ms total).

Repeating it for 66 times == 990ms

+10ms of delay == 1s.

Each time print a different number for each display.
