Congratulations to all the book winners.

I hope you enjoy it and find it useful

Thanks
Martin

I'll do my best to keep answering questions

Dependent on electrical noise levels a higher baud rate would probably be less stable, but you could always use some form of error checking

Yes you should be able to make your own metronome.

The figure on the front of the book is taken from a 19th-century edition of Sylvain Marechal's four volume compedium of regional dress costumes published in France and is entitled "Travailleur de deplacement" which means an itinerant laborer.

The link should be working properly now.

The camera isn't plugged into the Arduino it's a low light cctv camera on a seperate wire.

I'm 49 and remember those heathkits very well.

I think that will depend on the machinery and if it is electrically supressed or not

Hi Gavin

it will depend on the specifics of your project. For example how far the Arduinos are apart there are a variety of communication protocols you could use including good old serial.

The minimum requirement is really an Arduino UNO, most projects and code are based around it, although we do cover the Arduino Mega as well

we don't really cover what the choices are with an embedded processor, things in that field are changing very rapidly with the Raspberry pi causing quite a disruptive shift. I've worked with both a Beagle bone and a Raspberry pi for video processing and am looking to use the new Beagle bone black shortly.

There are a number of ways of achieving what you want. I've been using an Arduino and an Xbee breakout board with a WiFly RN-XV module that has been very easy to set up and use, Jordan has good experience of using Arduino wireless shields and hopefully he will chime in with this discussion.

Hi Venkat

it all depends on what 'Real world' projects you want to do. The Arduino is great for prototyping projects, the BBB allows you to achieve more complex projects requiring greater computing power.
Really it's a case of fitting the processor to your project and using the most suitable.

I personally would go with an Arduino UNO there have been a few minor teething issues with Arduino Leonardo and some libraries.

I think the Arduino is a good stepping stone. The Arduino IDE hides much of the complexity of connecting to different sensors and objects. The book has a number of projects that could be built by kids just learning.

I think my coolest is an Underwater Robot ROV http://www.underwaterrov.net
