I want to make a project which can control 15 object using rf module

Permission granted.

Did you have some specific RF module in mind? What will it be communicating with?

but my program is not working

You have not posted any code, any links to any hardware, or described what the code actually does or how that differs from whatever it is you want. So, all we can offer is some fake sympathy. If we were so inclined; I'm not.

so please help me

by doing my work for me. I'll pass.
