/* Welcome to DmxSimple. This library allows you to control DMX stage and
** architectural lighting and visual effects easily from Arduino. DmxSimple
** is compatible with the Tinker.it! DMX shield and all known DIY Arduino
** DMX control circuits.
**
** DmxSimple is available from: http://code.google.com/p/tinkerit/
** Help and support: http://groups.google.com/group/DmxSimple */

/* To use DmxSimple, you will need the following line. Arduino will
** auto-insert it if you select Sketch > Import Library > DmxSimple. */
