What is an "ldr" sensor?

Once you explain that, you might be able to read the manual on it to see how to connect it, or someone on the forum may have a tip on how to connect it.

No one is going to make a VI for you.  Make your own and if you run into problems, post it here and people will help.

I would recommend looking at the online LabVIEW tutorials
LabVIEW Introduction Course - Three Hours
LabVIEW Introduction Course - Six Hours

LDR guess is Light Dependent Resistor aka photocell.

You did the "tell" part of "show and tell".  Now it is time for the "show" part.  Upload your VI.
