Here's the first set, chaps.

Thanks!

Hi all.

Thanks for taking the time to help me with the questions to produce the world's first Art of Electronics Answer Guide.

Yay!

I intend to post questions up here. Any which need a schematic or formulae from the book will have that too.

In order to avoid people doing the same question, could you please reply and say which questions you want to do.

When you have worked each out, can you please send the workings and answer to...

No questions to answer this time!

I had an hour last night to begin reading through the book I bought. The first chapter served, as one would expect, as an introduction to the concept of the microcontroller (from now on uC) and gave a basic layout and description of the parts which make up a uC.

Bascially, four parts. You have the Central Processing Unit, Input and Output Devices, Memory and Buses.

The CPU manages the uC. The memory acts as a storage area...

Well, a lot of views for my first post, and I'm very grateful and happy some people have found it useful! Even rated 5 stars!

What I'll do is address any questions I recieve, by PM, email, on the forums or even as a comment at the beginning and then add the new post.

Questions from #1:

1. Is LFEBS12UB backwards compatible - ie, with XP or Vista?

The important thing to remember is that the board itself should be compatible with any computer...

I hope that this blog will serve many people who, like myself, could not find a definite and easy to understand list of the needs and the progression towards learning to program a microcontroller.

In this, my first post, I will talk briefly about my time trying to find a microcontroller to begin with.

At first, I started with a development kit made by Velleman. It was very simple, having no inputs or outputs built onto the board. It was up to you to screw components...
