Using a 595 to control a 7-segment LED display
Courtesy/Thanks to: Anything Arduino
Description: This simple sketch and accompanying video shows how to connect an Arduino to a 7-segment LED display using a 74HC595. In the files section you will find the diagram with the binary values for displaying the numbers on the seven segment LED display. Also the sketch

this is ok
