In this tutorial I will show you how to flash a LED light with Raspberry Pi and Java. This will be a complete step by step tutorial starting with connecting the cables, trough GPIO explanation and finally writing the java code.
Fans of the Raspberry Pi were astonished to learn that a powerful new model is being released, an announcement that came just a couple of months after the Raspberry Pi Model A+ and Model B+ flew off virtual shelves.
[Gr4yhound] has been rocking out on his recently completed synth guitar. The guitar was built mostly from scratch using an Arduino, some harvested drum pads, and some ribbon potentiometers. The video...
today we’d like to spend a few words on a sparkling project of our friends of #Toi, ThingsOnInternet, that we first met at the RIOT Internet Festival last year in Pisa – and it has been a good idea indeed to take part to #RIOT, given that from that starting point BETaaS and Viper, two brilliant ideas UDOO-based or UDOO-supporting, have sprung. Viper moreover is already gaining a small (but remarkable, considering the timing) success in Italy – where the founders come from – with a coverage by Wiredand Corriere della Sera! How could we avoid to make a post about it?
Twitter telegraph is a project by Devon Elliot making telegraph sounder tap out Twitter messages using Arduino Uno. It’s an interesting attempt to connect technology rooted in the 19th- and early 20th-centuries with 21st-century networks:
I have experimented with reading an Arduino signal into R in the past, using Rserve and Processing. Actually, it is much easier. I can read the output of my Arduino directly into R with the scanfunction.
Summary: The Raspberry Pi 2 Model B is a simple, more powerful, upgrade to the original Pi that comes with a good range of bundled applications. The Pi 2 is great value at $35, but a number of additional items are needed to turn it into a fully functioning system.
Here’s how to build a buck converter using an Arduino Nano (as well as another 28 listed components) to supply the maximum power that you can to your PV cell. This is known as maximum power point tracking, abbreviated MPPT.
After a few hours of work alongside an electrical engineering buddy this week, my home garden drip system became powered by a Raspberry Pi. I can control the entire thing locally from my iPhone and, to be frank, it’s pretty flippin’ cool.
For the last 15 years or so, software synths have slowly yet surely replaced those beatboxes, drum machines, and true synthesizers. It's a loss for old hardware aficionados, but at least everyone wit...
SparkFun Blocks for the Intel® Edison are a great way to unlock all the features provided by the miniature 70-pin expansion connector. By mixing and matching Blocks, users can custom-tailor their Edison for any application. To get started, let’s look at the anatomy of a stack of Blocks.
