Set parameters after compilation I am extremely new to arduino and have searched for this on net but have not found it.
My project has 2 files, a &quot;.ino&quot; file with the sketch and another &quot;.h&quot; file with the secrets and configuration parameters, such as reading intervals, credentials to connect to Wi-Fi, etc.
Now I need in runtime to be able to connect to the arduino, either by serial or by any other way to be able to set these parameters.
Edit:
My question is: How can I change the parameters after compiling the sketch ?, for example, how can I specify the credentials for the arduino to connect to the client's wifi, since each client has different credentials.
It is likely 2 features are desired for this project:

A way to enter WIFI credentials after the program is running.
A way to store the WIFI credentials between power cycles.

The solution for the 2nd requirement is to use non volatile memory. Both problems have been solved before for certain types of Arduinos.  Here is a project on GitHub which has solutions for boards using the ESP8266 or ESP32 processors.
