How contol a 7 segment display with the Arduino.

I builded a 7 segment display controlled with a Arduino, wich can receive chars (more than 1 in time) from the serial port (for example from a c++ programm, like i did) and display them (1-9, 0, a-z).

There is a little problem with one of the wires. 7 Cathode is not connected, which is the one that is supposed to go Arduino Pin 4. Currently pin 4 is connected to Anode 8 which is ground. Otherwise, thanks for your share!
