We created a system for projecting light through a screen. When the event is 15 minutes away, the LED ring turns on, creating an image around the door that cycles through various colors. As the event nears, a conveyor controlled by two servo motors brings the LED ring closer to the screen, enlarging the image, and the rate at which the colors change increases as well. The conveyor can be reset to respond to the next event. Code, schematics, and additional documentation can be found below.
Is this a good/useful/informative piece of content to include in the project? Have your say!
