Here’s a video of the whole thing in use!

Using the python library, tweepy, getting the twitter interaction to work was actually very simple. The downside is that I can only retrieve mention data every 60 seconds due to Twitter’s API rate limiting.

The circuit is very simple, the RGB led strip I have is common anode, so I used N-Channel mosfets attached to pins 18 (Red), 23 (Green) and 24 (Blue). For the camera, I’m using a spare raspberry pi camera module I have.

For the names of the colors you can write to the lights, I went with the 140 X-11 colors. I figured it was a good spectrum of colors.

The source code for the whole project will keep getting updated, so check here for the most recent versions of each file.

I’d love to expand the scale of the project, if you’re a student at wpi and would like on of these in your window, please email me at the addressed listed in the about section of my website.

Thanks for reading!
