Basically I believe I have a single 7-segment display wired up properly thanks to some help from CrossRoads, but I'm a bit at a loss with what  to do with the the programming part of it.

I have this 7-segment display:

and I used this shift register:

My eventual plan is to have 2 displays of 4 digits each. I don't need any counting or clock code. I just need to display numbers.

I may need help displaying numbers as they are being entered into a keypad, but I'm not sure at this point.

There's a good tutorial with code examples for the shift register here:http://arduino.cc/en/Tutorial/ShiftOut

Take a look at my project in the exhibition forum.

I used the code from the danger shield and the keypad library to display some numbers keyed into a keypad.
