I’m not sure what you’re asking. Do you want me to help you purchase holiday lights for your roof?

Wow! That sounds like a pretty advanced computer problem, to me!  For starters, you would need a computer that is capable of visualizing your home, like a CAD (computer-aided design) program, and you would then need to learn how to code an algorithm that would allow you to control a “digital paintbrush”.
