Of course. I decided to use 80 valves ( maybe whole system will be pressurised and I'll be using nozzles instead ). Because of the financial reasons I can't use more.
Plan is to use 10 8-bit shifters to communicate between microcontroller and valves/nozzles. Since that I ordered arduino mega ( with 54 I/O pins ) with V3 expansion board, I might be able to skip all that ( shifters ) and connect valves/nozzles directly to arduino.
Making sketch in arduino shouldn't be a problem, but because of the lack of memory on arduino I'm gonna need some external program to send binary image through arduino to v/n. I see that it can be done in VB, and that's ( for me ) the biggest "problem" in whole project. Don't know how to do that...
