By monitoring a stream of tweets coming through Twitter, this mood light changes color based upon the frequency of words such as “angry, happy, or sad.” The system uses an Arduino which collects data from Twitter using a WiFly module. After the analysis, a mood light displays the current mood of the world through RGB LEDs.
The system above features an Arduino with the WiFly shield attached to it. Definitely a great starter project to learn about connecting and controlling your projects remotely. Check out some of our similar projects below:
