Interfacing Leap Motion with Arduino and node.js

 Ever wanted to control something with the wave of a hand? For many people it's a dream that can't be fulfilled via normal means - until now. By using a combination of technology that begins with a Leap Motion control device and finished with some Arduino-controlled servos an example of this has been created which controls a typical desk lamp, allowing one to move the lamp head up and down, and also left and right. 

The software interface is a node.js application which connects to the Leap Motion SDK websocket server, and the Arduino simply runs the Firmata sketch and a little extra code. It may seem complex, however definitely worth the results - for example:

So science fiction can start to become reality with Arduino! Find out more from the Xavier's demonstration page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're new to Arduino and want to join the fun, the first step is a solid board for your projects - our Freetronics Eleven - the Arduino-Uno compatible with low-profile USB socket, onboard prototyping space and easy to view LEDs:
