For Microsoft Build 2014, the Internet of Things team at Microsoft put together a very cool Netduino-powered traffic light.

Here's what it looks like on the inside:

The software powering this cool project is based on the awesome Bitcoin + Azure code written by our very own Matt Cavanagh (roguemat).

Microsoft's Steve Teixeira showcased the traffic light, controlling it manually via Bluetooth from a Windows Phone 8.1 device in the Build 2014 IoT Session

The Netduino Plus 2 inside the traffic light can also pull down Bitcoin data from Azure in real-time, displaying the value changes as they happen (green = value going up; yellow = value steady; red = value going down).

Here's a great blog post by Matt Cavanagh, explaining how to put together your own Netduino-powered Bitcoin Traffic Light:

And here's a quick video of the demo in action (with an RGB LED instead of the life-size traffic light):


This same code could be reused to indicate when a big software build completed, to indicate the current air quality in a building, to warn of little-time-remaining in a meeting, etc.

Thanks a bunch to Matt Cavanagh (roguemat), to the IoT team at Microsoft and to Philip Lo and his NETMF dev team at Microsoft for enabling, building and showcasing this IoT demo at Build!

I was really surprised how affordable LED traffic lights are. Also...from their reaction, the TSA agents apparently didn't expect someone to bring a traffic light onto a plane ;)

Wait, this isn't a normal occurance?! Shameful!


I make Windows Phone stuff for beer money and rent (in order of priority). I've got a blog and am on the Twitter machine.
