Using our DIY chipKIT-board tutorial, Darryl Gardner, a student of the University of South Florida, created something he calls the "Man Cave Sign" for his MakeCourse. This techie sign not only displays messages (via 5 LED dot matrices), reacts to playing music, and lights up in different colors (via 2 LED light strips), but is also controllable via Text Message or Android Apps (which he wrote) that allow the user to do many things like change the display message, control the stepper motor, the color of the light strips, and even make your phone talk out loud!
His PIC32BLUE(+) Android App and PIC32BTN Android App allow you to connect to your microcontroller using a Serial Bluetooth Module and do various things like send messages/commands to/from your Android phone and control things like servo motors, LED matrices, RGB lights, LCD screens or anything you'd like. He incorporates other technologies as well, like a microphone to adjust the light strip colors according to sound fluctuations in the room, a stepper motor to rotate a USF Bulls logo, and he powers it all with a 10,000mA battery for a battery life of over 10 hours.
In this Instructable, he provides more details along with a YouTube playlist of some Arduino tutorials he referenced for the project. Keep an eye out for more details on the various portions of this project! :D
