Working with a cathode-based LED seven-segment display
A simple common anode display like you have is just the opposite of a common cathode display. Just reverse (invert the logic). Connect the common pin to V+ (5v for a regular arduino), and each segment pin to an appropriatte resistor then to the arduino pins.

Since you are inverting the logic HIGH turns off the segment, LOW turns it on. The arduino pin acts like the ground. Simple.

Just keep in mind the arduino pin and port current limits.
