Like @caitlinsdad implies, you haven't given enough information.

Your first step should be Google arduino and LN987N. :!

What kind of arduino are you using? Have you already set that up and able to code it?

Do you have the proper libraries(drivers) for your components?

What is your wiring schematic or setup for the components and the arduino?

Sure, what do you offer per hour of coding? ;)
Simply check the corresponding code libraries.
