Designed what, exactly?

How can you say that you have "designed" it, if you have no idea how to operate it?!

what will be the logical inputs to the udn and uln ?

That's back to the Datasheets & Basic Electronics again:

i want to know how could i control this with softwares

You need to know how to do it without software first!

Do you have any programming experience?

                           It appears you need latching relays      Richard Erlacher      05/20/11 06:49      
                              Latching relay is still slow      Per Westermark      05/20/11 07:46      
                                 You're right, but the relay spec's should reveal that      Richard Erlacher      05/21/11 08:26

                                    SPI + latched shift registers are good choices      Per Westermark      05/21/11 09:38      
                                       The protocol is good ... but not necesary here      Richard Erlacher      07/04/11 10:21      
                                          SPI is excellent for driving long shift registers      Per Westermark      07/04/11 14:38
