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.

    Alex,

         First thing to learn is "Google is my friend". Here you can have an idea and see what people have done, Surprisingly, many beginners never learn that. I agree with both and

    They have done a great job for many folks like yourself. Arduino is a complete package with processor 8 bit, some flash space, SRAM, and digital and analog (PWM) for I/O inside a DIP. You should use your friend and look up each.

    When you do you have started on a great journey of fun and excitement when you see the possibilities. We will be here and can help you along when you get more specific questions. It always help to bring as much as you can in the post.

    You will find the community is very understanding since we have been in your shoes (I know I have had many silly questions).

    I hope this helps motivate you to try some of the following:

    • Build on a breadboard the extra things to make a ATmega328p into a personal Arduino.
    • Make a buzzer project that can act like a simple alarm clock.
    • Use LED's to act like a traffic light.

    Just some random ideas that you can try,.
