Connect your Udoo Deejay Party to a screen and amplifier, a simple interface will allow to start your party by choosing a set of (Youtube, Vimeo, etc) videos to be displayed on the screen or projector. An integrated application will drive your lights (led strips and led spots) and possibly other visual effects like lasers, smoke and moving lights. Most of the action is music-controlled, just hit "play" to start!
Mount a led spot on one or two servos to control its light direction, use a multiple-colors one for even greater results.
Mount a laser generator on a small motor to make simple light effects, a servo moving the motor is a plus!
Let strips are now popular, but the best is if you can control them based on the music playing and/or based on the dominant colors of the video playing on your screen/projector.
Just use one of the output pins to control a smoke generator when required.
Add a camera and show your party dancers on a giant screen or projector, mount camera on two servos to move it around the dance floor.
