Daisy-chain Arduinos for very simple networking

 In order to support controlling various Arduino-compatible devices using the simplest manner possible, Scott Lawrence has concocted a simple system that daisy-chains the serial port of each Arduino do the next. Then a master Arduino can send data down the line to each subsequent Arduino, and they can take action if they recognise the command, or pass the data on to the next. My memory is a little vague but this reminds me of the Microbee Beenet system. Nevertheless Scott's system is simple and works - and sometimes that's what we want. 

So click here for the details, code and a demonstration. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're looking to embed one or more full-sized Arduino-compatibles in your project but would like to save some money, consider the Freetronics KitTen. This has all the features of an Arduino Duemilanove-compatible without the USB interface and is in kit form, saving you money while staying true to the Arduino form. For more information and to order, check out the KitTen page.
