Ah good!

And thanks.

Hi Pedro, please try again and let me know.  The link is okay for me. I have had DNS problems fairly regularly with my host, and I get the feeling it might be region related. Where are you in the world?

Can you post a table of contents ?

Sure. Converting the PDF to something to paste into a forum post proved impossible. I have put a PDF of the table of contents here:

My new book 'Programming Arduino Next Steps' is out on Amazon now!

Its the sequel to my book Programming Arduino. It deals with some of the more tricky stuff.

Thanks Rob!

It's not a matter of hardware but community and online resources.

It is, and it takes time to get that. It also requires that (in the case of BeagleBone Black) the professional electronic engineers who start the project, let go as soon as they feasibly can and trust the enthusiasts take over. I think BBB is getting to that point. Once its stable enough they need to stop messing with it and let the community start churning out the equivalent of libraries and shields. Not to mention books and all the fantastic online project write-ups.

I also agree that there is nothing quite like this forum. A couple of years ago I used to contribute a lot. I occasionally try now, but invariably when I come to a question I could help someone with 3 people have already answered it well!

That's really evil smiley-wink

I suppose to be really evil, there would be a very subtle bug in every sketch.

I did write a book with some fairly evil projects in, but it never sold that well.

'15 Dangerously Mad Projects for the Evil Genius'. http://youtu.be/JdZu4nExmJQ

Disappointing really - I think it is one of my better ones.

There is something strange going on with my DNS. Can anyone confirm this page is or isn't there?

Thanks, Si.

For those projects that an Uno can't quite reach. I have written a short comparison of these two boards.

.. is out now.

Images improved, old projects improved and some new projects.

12  Community / Products and Services / Re: Arduino Protoshield Project book out - by Simon Monk on: May 17, 2013, 07:44:10 pm
Hi, it was a self-publishing experiment, and did not sell so well, so it will become (all being well) part of a much bigger Arduino shield project book appearing later this year, with TAB / McGraw-Hill.

This includes several chapters on using Arduino.

Also have a look at PyFirmata:

https://github.com/lupeke/python-firmata/

The basic idea is a standard sketch runs on the Arduino and you turn pins on and off, set pin modes etc with Arduino-ish Python commands.

Its pretty neat.
15  Using Arduino / Sensors / Re: Using HC-SRO4 distance module and generating tone at the same time? on: May 03, 2013, 10:24:13 am
The rangefinder really doesn't need a library. This code is from my book 'Hacking Electronics' p 155.

Code:
// range_finder_budget
// Arduino Uno or Leonardo

int trigPin = 9;
int echoPin = 10;
int gndPin = 11;
int plusPin = 8;

int lastDistance = 0;

void setup()
{
  Serial.begin(9600);
  pinMode(trigPin, OUTPUT);
  pinMode(echoPin, INPUT);
  pinMode(gndPin, OUTPUT);
  digitalWrite(gndPin, LOW);
  pinMode(plusPin, OUTPUT);
  digitalWrite(plusPin, HIGH);
}

void loop()
{
  Serial.println(takeSounding_in());
  delay(500);
}

int takeSounding_cm()
{
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  int duration = pulseIn(echoPin, HIGH);
  int distance = duration / 29 / 2;
  if (distance > 500)
  {
    return lastDistance;
  }
  else
  {
    lastDistance = distance;
    return distance;
  }
}

int takeSounding_in()
{
  return takeSounding_cm() * 2 / 5;
}
