Animating a lamp with the Leap Motion

LeapMotion Arduino Hack for a lamp. Interesting to experiment with Node.js

The Leap Motion is a very cool device, but so far we haven’t seen many applications of interacting with physical devices. [Xavier] wanted to control a cute servo animated desk lamp with his hands, and with the help of a Leap and an Arduino he was able to do just that.

The Leap Motion API has a handy feature that will output all its data over a websocket. It’s a very easy way to transfer hand positions with a minimum amount of overhead, and with just a little bit of Node.js, it’s only two lines of code to connect the Leap to a websocket server.

With the Leap data on a web server, the only thing left to do is pulling it down to an Arduino. Again, [Xavier] used Node.js, this time in the form of johnny five, a Javascript-based Arduino framework. After that, it was a simple matter…
