Maybe, this will help ?SH5463AS Demo.
This is an example of how to drive a 7 segment LED display from an ATmega without the use of current limiting resistors. This technique is very common but requires some knowledge of electronics - you do run the risk of dumping too much current through the segments and burning out parts of the display. If you use the stock code you should be ok, but be careful editing the brightness values.
There are several web sites and schematics on the web that suggest you can attach an LED directly to an Arduino output pin with no current limiting resistor. They are wrong, and following them will damage your Arduino. Their logic goes something like "the arduino will limit the current" or "as you are multiplexing the LED (turning it on and off rapidly) the circuit won't heat up enough to burn anything out". They are wrong.
