Thank you guyz for helping me out, i'm quite blury when it comes to this, thats becouse i dont have the big picture of how its all connected to eachother, software, languages, hardware(readymade souch arduino and alike), and electronics ofc.
Reason why your input is of souch importance to me before i go and learn stuff is, i'm acquainted enough to know learning this stuff is never ending process, so better start with right stuff.
Just to make it clear, i didn't ment to say that arduino is not powerful, merly that i would like to become quite a knowledgable person so i can work with more hardware platforms depending on what i need.
For instance, i was told that arduino can do anything you want, but when useing 2 arduino serial connection over longer distance ethernet cable, it is not recommended to use arduino base for video streaming onto small display (for this matter, handheld controller with display, no aditional computer). Not enough speed/memory or something like that, and thats something i really need for my ultimate project one day, but theres no rush, get my basics straight and slowly work my way up.
Also, i'm certantly gonna learn more languages, even from my beginer perspective it was obvious to me that this aint gonna happen if i learn just one thing and now when you advised me to learn more than one, i'm gonna do just that.
Again, thank you so much for helping me out.
Regards
