Newbie question: how to build a valid circuit

Hi,

I just finished reading "Getting started with Arduino" and was able to get all the tutorial projects working.... very cool! :slight_smile:

One thing I feel the book is missing, is a proper explanation of how and why a circuit actually works like it does, explained in the same way as the programming language is explained. (i.e. written for someone who knows absolutely zilch).

My understanding currently is: if all your components in your breadboard don't add up to 5 Volts, you need to put a resistor in so that your breadboard components consume all of the 5Volts of Arduino's power.

But what if my components total more than 5 Volts? What if some are in series and others are parallel? How many components can I even use? :cold_sweat:

I hope someone can point me in the right direction!

My understanding currently is:

...a long way from the reality of it all.

My favourite reference is "The Art of Electronics" by Horowitz and Hill

I'll second that, and add Grob's "Basic Electronics" to the list as well (personally, I prefer it over the former, but both are good books to own).

:slight_smile:

Yep I don't think you can beat "The Art of Electronics".
I like the sections where they explain things and then give you schematics and ask "why would this circuit not work".

How many components can I even use?

Well in my last job the box I was making had over 8,000 components so it's quite a lot. :slight_smile:

Thanks for the recommendation, guys.

Hey OP, ((Copyright infringment removed by administrator))

This one is valid ((Copyright infringment removed by administrator))

Not telling you what to do or nuthin', but please seed

Is that a legitimate free ebook, or a pirate?

I really can't condone pirated IP.

And its worth looking around on the web for electronics tutorials - there will be some good ones out there pitched at the beginner (if you can find them!)

I am putting a vote in for There Are No Electrons: Electronics for Earthlings. It starts about 10 steps before the fantastic Art of Electronics.

For an on-line resource, this site:

Is not bad.

Thanks for all the replies, I've certainly found some material to dive into :slight_smile:

I guess admin answered that. I treat books much the way I treat music. I download via torrent and if I find that I like the entire cd, or book, I'll buy it (I think my bank statements would prove that). There is no replacement for a hard copy in your hands book, just like there is no replacement for an actual pressed cd. I guess if I were at one of you guy's house and tried to read through your copy that would be illegal too. I call it sharing, I don't really care what other people call it. A crappy scanned pdf is not just as good as a book book, it's a way to try before you buy and know that this book is either for you or not. It saved me from buying a copy of the getting started with arduino book. Once I scanned through the pdf I knew right away that I didn't want it.

I'll just have to remember this site is super anal about such things.

It's nothing to do with being anal. It's a liability to link to illegal material. Their legal protection comes from showing that they police the posts.

Also: stealing is bad says the guy who was downloading Terry Pratchett ebooks to read on my Palm IIIc in 2000. To be fair, I bought the hardbacks first, and later admitted it to his agent.

I buy when I like. I'm a book lover. PDFs don't do it for me.

I will take this moment to point out that the book I recommended above is available in kindle format AND good old paper for the tree fetishists.

The word 'tree' is protected under copyright laws. If you could use term 'non-animal life form' that would be great.

No worries, in this instance it's covered by fair use
