The generic wiring. NOTE: the 7-segment-4-digit display in Fritzing had some unclear wiring. You should be able to figure it out for your 7-segment display: the pins for digit-part A through G on the 7-segment-4-digit display connect to the 74hc595 the 4 cathode pins for pins 1/2/3/4 connect to the Arduino, pin 7/6/5/4
