Hi. I'm new to Arduino and would like to understand better the shifting process with a 74HC595. I started a project with 2 shift registers, one quad led display and a couple of led's (the links are below) .One shift register is reserved for lighting 8 leds and the other for lighting the display with which led is pinned High in the exact moment : LED1, LED2 etc. ... but here is my problem: i can't make it work, the display part at least. Can't even light a digit, or one single segment. I don't understand how to light up a 4 digit 7-segment display with a shift register and control it's segments and digits at my will. I'm not at my desk for the moment, can't let a code for revision unfortunately. In 3 days i hope i can.
My hardware connections for my quad display is the following:
-four digit pins i connect them to my Arduino board (4 slots-4 digits);
-my seven segments pins i connect them with the shift register, the last having also 3 wires connected to my arduino board (data, latch, clock);

Any code to understand a 4 digit display led connected to a shift register would be hepful.
