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.
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!
