Nobody is going to have program for you or will provide you a program.
Is this a school project?
The first thing is to figure out how you would program this if you were using any kind of programming language.
Then I would recommend looking at the online LabVIEW tutorials
LabVIEW Introduction Course - Three Hours
LabVIEW Introduction Course - Six Hours
Start programing your idea in LabvIEW, then when you get stuck at a particular point, then you can post here with any specific questions you'd have.
