/* This program allows you to set DMX channels over the serial port.
**
** After uploading to Arduino, switch to Serial Monitor and set the baud rate
** to 9600. You can then set DMX channels using these commands:
**
** <number>c : Select DMX channel
** <number>v : Set DMX channel to new value
**
** These can be combined. For example:
** 100c355w : Set channel 100 to value 255.
**
** For more details, and compatible Processing sketch,
** visit http://code.google.com/p/tinkerit/wiki/SerialToDmx
