Hi guys,
Hope you all doing well.

I want to start a business by solving small problems of day by day life routine.
To the Point: I made a Arduino project which is a device gives you time, weather, etc...(20 pins required ---> 17 is I/O, 1 is 5v, 1 is 3.3v & GND)
but I don't know how to convert my Arduino project into a chip as a embedded system and how to make it cost effective?

please help me, how to do it?

  1. any suggestions, should I use Arduino as embedded system or any other best solution!...

Thank you

You should read most of the articles on this page before you decide to proceed:
Compatible Products – Arduino Help Center
There are legal issues that you should consider.

But to make a PCB with all of your stuff on it you can start by learning KiCAD:
KiCad EDA - Schematic Capture & PCB Design Software
I'm just learning it myself.

You'll also need to understand the Uno's schematic:

Like you want to put all this on one chip?

Or

You want to make something like we all carry around with us already, but somehow yours will be better.
