Hi All beautiful people,
I want to create a home automation system for my home. I could buy a pre-built service but I always wanted to learn about IoT and this is a use case I can work on.
I don't have knowledge of Hardware, so need you guys to help me select hardware through which I can control lights and fans to start with.
I have read many places about Arduino and Raspberry Pi. People are building some really cool stuff with these.
For coding, I will use NodeJS to create connection and API's

Your best option is using a microcontroller, that is, an Arduino or better yet an ESP32 or NodeMCU like Yannik_Sc said, because it has a wifi interface.
With this microcontroller and a relay to toggle the lights you can then create network endpoints which are activated via wifi with a standard http request. You could then set-up a raspberry pi as the main gateway to your home automation network with a web frontend made in NodeJS.
I second the ESP32. I've been programming them using MicroPython to build various IOT / robotics projects. The dev board that I've been using costs $10 USD, with the standalone module costing ~$4 USD.
Thank you Damian, You actually cleared my doubt on creating a network and handle it. :)
Hi Ghazi.. Arduino and Raspberry have different purposes (Arduino has a microcontroller built-on and Raspberry doesn't). I think you should consider that for Arduino you need a little bit of C knowledge but on the internet there are as many tutorials as you need.. If you want to control light and fans my opinion would be to choose Arduino..
Thank you Eduardo. Yes, I want to control lights and fans for now. Maybe I will add more controls in the future. But what I want now in feature is that I should be able to control these switches through the internet.
Yes, definitely you can.. there are solutions like ESP8266 with a TCP/IP completed stack and it is very cheap
Thank you I will check this for sure. :)
Raspberry PI if you want network, parallelism and a more or less known environment (it runs Linux).
If you only need network and "single threaded" applications as well as a small form factor you probably want to use a NodeMCU/ESP.
If you can go completely without networking and you use a serial bus or something like this for communication (if you need it at all) you may choose the Arduino.
However, the ESP and Arduinos are mainly programmed in C/C++ (some also run Lua or Python). You should keep this in mind when you get to your final decision.
For Node.JS however your only choice (as far as I know) is the Pi. But in the end they all can do the same for IoT. Only the available libraries are different on the Raspberry vs Arduino (which includes the ESP and NodeMCU).
Thank you for your deep insights into this :). It will surely help me to get prepared for this.
I want to create a system that I can control from the internet as well, so if I'm not at home then also I should be able to control switches.
