Can someone please help me with the Stuff about Home Automation . I saw various videos on but none of them had made it very clear about their connection and not even good expalation . i don't want whole ready mate project all i need is just how to start with it ? what could be my basic first step to understand my project well.
i have very basic idea about arduino boards but don't know its proper usage and configurations.
The key to getting some help is in refining what you mean by "stuff" (and also returning to the board to see the responses)..
I read your post and the title carefully and from what I can gather, you want to automate lights in your home using an arduino. You have not stated that you want to automate your lights over the Internet using your phone, for example. With that it mind, I think post #3 has some good leads for investigating several techniques.
Several other posts have discussed IoT based approaches.
Let me talk about another very simple, yet effective, approach that you may be able to understand as a good starting point.
Start with the endpoint - the lightbulbs and/or the sockets that the lamps connect to. Here I am assuming the line or mains connection. As a beginner, I would advise that you not try to build that part. Instead, purchase those parts. For example:
Those are remote-controlled light bulb sockets. They receive 433MHz RF to turn them on and off. Your remote controller functions as the transmitter and the receiver is built into the socket.
Here is another example:
Those operate in the same way, but instead of turning on the light bulb socket, they turn on whatever is plugged into the socket (which, of course, is plugged into the wall socket). I think those are also 433MHz, but you need to check as some are 315MHz. These are all pretty low-end.
So, now, the question becomes, how do you get the Arduino to take the place of the remote control transmitters that they come wth. Fortunately, there is a lot of work done with that.
First, you can get some 433 MHz transmitters and receivers that can be hooked up to an Arduino:

Then, you first have the Arduino read the RF communication from the remote. Once read, that information is stored and can be transmitted by the Arduino from within a program.
Here is a good multi-part tutorial on that process.

There are many such tutorials.
Here is a good library for use with the Arduino:
Arduino lib to operate 433/315Mhz devices like power outlet sockets. - sui77/rc-switch
So, armed with those basic tools, there are a couple of points to consider. First is that these will have some limited range - maybe 80ft, maybe less, maybe a little more.
Second is that you will likely want to add a real time clock to your Arduino so that the automation is accomplished at certain times and under certain conditions.
This approach, I think, gives you a good, low cost, foundation for the "stuff" that you mentioned.
It is only one, relatively simple, and relatively hands-on, approach. Go back to post #4 as well as the IoT methods that were mentioned.
