yasmin,

You need to ask clear questions if you want good help.

What is LDR? Bridge circuits usually have four branches. Does each LDR have two branches or is something else used to complete the bridge?

What do you want LabVIEW to do? Does it monitor the output of the bridge? Does it control the tracker? Does it interact with human users? Does it save data to files? How fast do things need to happen? What should it do if an error occurs?
