1  Using Arduino / General Electronics / Re: Interactive Traffic light - button doesn't work on: July 06, 2012, 05:28:56 am
Hello All

There is an error webpage for this book at...
Look under the "ERRATA" Tab
You can also download the source code
at the same place, its a zip file.

For this project, the error sheet says.....
On page 41:

near the end of project_4
following this line:
digitalWrite(carYellow, LOW); //yellow off
add this missing line:
digitalWrite(pedRed, HIGH); //ped red on 9
It seems to me that anyone can post a correction...
At this point, I'm working on project 6, Interactive LED Chase Effect.
I'm very new to Ardunio. I do like this book very much.

Hello All.....
I thought a few of you might enjoy this.....
I am very new here, so I hope this post is OK??????

This year we commemorate what would have been the 100th
birthday of Alan Turing. He was truly the Galileo of a new
field now called computer science which is arguably the most
important scientific advance since the invention of the wheel.
A fascinating article (first URL below) recounts Turing's life,
explains how he correctly envisioned computers would work and
how he defined what we might call a "Turing Machine."

A Turing Machine is any computer so convincing that a human
cannot tell whether the unseen respondent is a computer or another
human. Today we have Turing Machines in very limited areas of
expertise, but a true Turing Machine is years away because it
would be able to converse and reason on any subject matter
whatsoever, and of course show and understand emotion.

Now the big question is when the "technological singularity"
will occur - essentially the arrival of the generalized Turing
Machine. Artificial intelligence has progressed to the point
where computers' reasoning power should be indistinguishable from
human brain power by 2029 according to inventor Ray Kurzweil in
a recent interview with The Wall Street Journal (second URL
below, subscription required).

The "technological singularity" will be monumentally
important in human history -- like landing on the Moon for the
first time but far, far more profound. It'll be interesting to
see if the 2029 date holds, and to ask the Turing Machine just how
it feels about the human race, and what it thinks will happen as
it clones itself and makes itself smarter than humans.

 Hi James,
Very Very nice...
This is better than any other "oven" I have seen so far!!!!
I have seen the "Hot Plates" on the Spark Fun site, Yours is
very good. Please keep us posted....
I just moved into a new place, I want to start making PCB's soon
and have never done SMT before. After seeing this, I have to
re think SMT, this looks very do-able....
Can you post a step by step on what you did ????
YouTube video would be great...
Thanks !!!!!

 Hello All,
So please tell us, How did this turn out ??????
Photos ??? Website ???
I am very new to Arduino, So I don't think I can be of much use.
I have been to the Field Museum of Natural History in Chicago
many times years ago when I lived out in the south suburbs ...
If you ever visit Chicago, do spend a day here, well worth it.....
5  Topics / Education and Teaching / Re: Mike McRoberts - Beginning Arduino on: June 20, 2012, 06:41:00 am
Hello All,
This is my first time posting to this forum, so I hope I am doing this right !!!!
I just ordered the Mike McRoberts book, Beginning Arduino from Amazon...
The main reason I ordered this book is that it had a lot of very good reviews,,,
I just hope the reviews are on target. I am brand new to Arduino, some programming
many years ago in Trubo Pascal and in C C++, but not very good at it.
I have tried learning the PIC in C, that did not go well !!!!
I am a semi-retired Broadcast Engineer and ham radio op, so the electronics side
should not be a problem at all.....
I have enjoyed reading some of the posts here...
