The Internet of Stranger Things #piday #raspberrypi @Raspberry_Pi

Nice project from Seb Lee-Delisle!

This year I’ve been running a workshop about using JavaScript and Node.js to work with all different kinds of electronics on the Raspberry Pi. So especially for 24 ways I’m going to show you how I made a very special Raspberry Pi based internet connected project! And nothing says Christmas quite like a set of fairy lights connected to another dimension.

What you’ll see

You can rig up the fairy lights in your home, with the scrawly letters written under each one. The people from the other side (i.e. the internet) will be able to write messages to you from their browser in real time. In fact why not try it now; check this web page. When you click the lights in your browser, my lights (and yours) will turn on and off in real life! (There may be a queue if there are lots of people accessing it, hit the “Send a message” button and wait your turn.)

It’s all done with JavaScript, using Node.js running on both the Raspberry Pi and on the server. I’m using WebSockets to communicate in real time between the browser, server and Raspberry Pi.
