Processing can also be hooked up to aaallll kinds of things, like Kinect, Arduino, a camera, or even just mouse/keyboard inputs. I like Fadecandy because it's cheap to get started and you can have heaps of control over your LEDs in a very visual way using Processing. You write code that places the LEDs across the Processing canvas, and then anything you draw in Processing shows up on those LEDs in real time. You have a canvas, just like you would in Photoshop or Paint but instead of drawing with the mouse, you draw by writing code. (You can connect multiple Fadecandys to one computer to increase this.) Processing is a programming language used to make visuals. Fadecandy is an LED driver which can control up to 8 strips of 64 pixels each. This is a step-by-step tutorial on how to use Fadecandy and Processing to control addressable LEDs.
