In progress...
The Arduino Output sink works in tandem with the Arduino shield to read and write digital I/O. Channels can be set to trigger output in response to a specified event channel in the GUI, or triggers can be piped through the Arduino as input. Alternatively several channels can be set to respond to a single trigger to sync many external devices.
Working on:
Clean up interface
Bug fixes
Reducing relay latency (currently ~20 msec)
Other functionalities?
