This video covers everything to get you started with Xlights and Arduino. The hardware being demo-ed in this video is an Arduino Mega 2560.

First. The example script that will get your started is here on GitHub:
https://github.com/mlivolsi63/xlights

Second: The Video covers the following:
A) Setting up your controller to talk to the Arduino
B) Setting up the layout
C) Creating an extremely simple sequence.

This video also covers things like "Output to Lights" which actually begins the process of sending bytes across the line.

WARNING: If you set the BAUD rate to 9600, the Arduino will not process the stream fast enough and a log jam will occur, and the display and sound will not sync up correctly.

The main goal is to take away the mystery of Xlights and get you started on your Generic Serial journey.
