Understanding how/why Arduino works?

Former Member

Hi, I am really interested in learning electronics (which I know virtually nothing about). I saw some videos about Arduino and RPi, and think they're really cool.

 

But I have one problem with these products. They're already made for you, and you simply use them. I can see how the Arduino can be useful for electronics projects, but it doesn't really tell me how/why the Arduino does what it does.

 

I would like to know how to create my own circuit, from scratch, that can do what the Arduino/RPi does. Is this possible, or too difficult?

 

I really want to have a low-level understanding of electronics. I don't know where to start, or what resources would be helpful.

 

EDIT: Like, for example, I would like to be able to get into the mindset of the people who made the Arduino/RPi, and understand how they made them and everything they knew about the various components (chips on the circuit, pins, capacitors, etc.)

 

Thanks in advance,

Alex.

    Thanks everyone for your kind help. I have looked into the advised book and the link, and while they look very interesting and detailed there is one problem that I have... Mathematics...

     

    I'm extremely bad at reading math. Is this going to be a problem?

    Forgive me for being repetitive. For I am going to repeat my Canned Answer for the newbie AM WRT RaspPi. I will have a similar critique for Arduino when I get around to it.

    AAR:

    WRT (With Respect To) S/W for the RaspPi there are Two

    Flavors

    1.

    Raspbian (Debian) O/S gotten at:

    www.raspberrypi.org

    2.

    Minibian O/S gotten at:

    https://minibianpi.wordpress.com/

     

    ------------------

    I personally have Two separate uSD/SD memory Cards

    I boot-up w/ the card that will dictate what I want to do.

    Minibian for using the RaspPi to control/obtain Outside

    World Parameters.

    Raspian (Debian)  to use RaspPi as a general-Purpose Computer.

    __________

    WRT H/W for the RaspPi, there are also many options,

    but one is unique:

     

    This being the RaspPi Zero. RaspPi Zero is a stripped-down RaspPi

    Board that one would use AFTER you have developed your H/W &

    S/W on the Full-Function RaspPi Boards

    BTW the RaspPi Zero does NOT have connector for RaspPi Camera

    Module

    __________

    WRT to Learning/Receive-Mentoring about the RaspPi, there are MOOC

    (Massively Open Online Courses) courses on the web.

    To AM specifically: To do component Electronics is very hard today. When I got my BSEE in 1973, it was Easy b/c there was NOTHING else but Component Electronics. Nowadays it is the  Black Box(es) Approach. x -->{Black Box does f(x)]--.>y (=f(X)). B/c of Patents, copyrights, Trade Secrets, Companies RARELY give out Schematics. You have to do the best you can and adapt to this Black Box World (for it is practically All we have.) Unless (like the other comment(ers) mentioned) IF you have Unlimited Time & $$$, then you can go the Component Electronics Route.
