Who will help you choose modules for a smart home?

Question

Arduino

Hello. I want to experiment with arduino!
I want to do
1. So that the front door opens via nfc
2. Make a doorbell with volume control and play music from a micro-sd card
3. When someone rings the doorbell, video from the camera module is transmitted to the computer browser + so that I could communicate by voice with this person who rings the door
In terms of a web application, there will be no problems (I'm a web programmer)
It is advisable to give links to an aliexpress store, I don't need high-quality modules, I decided to buy just to "play around". If this topic "tramples" then I will delve into this area and then I will update the modules for better
ones. Can you help me with the choice of modules?
Thanks everyone in advance

Answer 1

No, it's too early to go to the store, you need to think over the projects of these inventions, think over how everything will work, and only order last. There are many nuances here.

Answer 2

Sergey, first make the door open by the nfc key and from the button from the arduino, without any connections to the computer, and after connecting the arduino to the computer (if necessary) - you can use this module (click) arduino any even nano. To play music from a micro-sd - such a module has a memory card slot and a sound output right away, if you can handle this, then you will already understand whether you need it or not. Next, deal with a camera with a microphone connected to a computer (you can’t connect a camera to an arduino) and combining all this goodness in a graphical web interface

Answer 3

I myself recently also collected something similar:
* Music is just wired melodies in MML format ;
* a notification about a call to the intercom comes to the phone and when the bell rings, the picture from the camera also arrives.
It all depends on what kind of iron. If a camera/registrar can only send RTSP, then you will be tormented with it, or you need an intermediate piece of hardware with Windows\Linux that will convert the stream.
