pls help me with it.
You go first.... post what code and circuit you have so far, explaining what is / is not working properly, then you'll almost certainly get some advice.
On the other hand if you haven't worked through the tutorials here, you should do that.
this is the circuit diagram i do not have the code for this.

Here's the pic for others:

Nobody's going to write it for you: you'll get help if you make a start, but you have to at least do that.

Actually, the code would be tricky because that is not a circuit diagram or "schematic" at all.
It seems you want to make something similar to fade. 
Go to arduino program->examples->basics->fade, and see if is that what you want.
