arduino bug 150x150 Light Sequencing and Decoding DMX with an Arduino
Akiba of Freaklabs and Tokyo Hackerspace wrote in with a three-part tutorial on using an Arduino to control complex lighting displays.

Now that we’re moving into the holiday season, we’re about to start seeing the hard core Christmas people setting up the elaborate light displays. The equipment to switch all the lighting channels and sequence everything is usually a bit costly but it doesn’t have to be. If you’re familiar with the Arduino environment and willing to put in a bit of elbow grease, blinging out your lawn is just a couple of mouse clicks away :)

I put this three part video tutorial together on how to use the Arduino platform to decode the DMX protocol. The DMX protocol is a standard protocol for stage lighting displays and it happens to be supported by a nice freeware light sequencer called Vixen. In the first part, I go over the DMX-512 protocol and the Arduino source code to decode it. In the second part, I show how to configure a lighting sequence with Vixen, some hardware implementations, and the whole system working together. And in the final part, I show how some simple changes to the code can enable you to control your lights wirelessly.
