Data Responsive Project

This project spins a continuous servo motor and lights two LED matrices in response to real-time data. The data is pulled from the National Institute of Standards and Technology CVE database, which tracks security breaches and vulnerabilities in software used worldwide.

Every five minutes, the program checks for an update to the database, at which point the motor spins, and the two matrices change their displays. One matrix displays an "evil" face to represent the hacker, and the other displays an "X," to represent the computer crashing.

Sorry the video is bad! Instructables won't let me upload a different one. Let me know if you need another one! :)
