For basic control of RGB Pixels

=====================================*/
/**
* VIXEN Setup:
* In Vixen display setup...
* - Add an element group containing one element for each pixel attached to arduino
* - Configure the 'Color Handling' as "They can be any color: Full RGB"
* - Add a "Generic Serial3 Controller"
* - Name it what you want (Although... Jdc928IsAwesome is great controller name)
* - Set the channel count to 3x the number of Pixels you have
* - Save, then configure these options
* - Com Port: choose the correct port for your arduino's Serial3
* - Baud Rate: 115200 (or whatever you changed it to below)
* - Click OK
* - Check the box "Send a text header"
* - Type "VIXStart" in the header text box
* - Click "OK"
*
* - Click and highlight the newly added Element in the elements list
* - Click and highlight the newly created controller
* - Your "Total Patch Points" and "Output" counts should match
* - Click "Patch Elements to Controllers"
* - Click OK and you should be ready to go
*
*
* You should now be able open a Sequence
add some effects to the new channels
and see the strips responding accordingly

/**
* Pixel Strip Setup
* Strips setups vary but generally as follows
* - If your using a large number of strips you will
* probably want to power them externally.
*
* - Connect external V+ to strip Vin
* - Connect external Gnd to strip Gnd
* - Connect external Gnd to Arduino Gnd
* - Connect Strip Data to proper pin on Arduino
* - Connect Strip DataClock to proper pin on Arduino if not using ws2812
