I'm working with an HD 810 My 8 buttons are configured like this: 0-3 = Input 4-7 = Output Currently I have the system set to have my outputs on at start up. When a button is pressed, a specific output turns off. (Button press to Input 1 turns Output 4 off) When the program is finished playing, the output is turned back on. Is there a way, using the BrightAuthor programming GUI, to make that Output cycle change from off to on, over and over, in .5 second intervals instead of just turning it off? Thanks.

  Yes,
  
  You have to setup an interactive playlist. In your interactive playlist, you can double-click on any file, click on Advanced, and Add command. Under Add command, there's a gpio on and gpio off settings. You can set any gpio that's set to output on or off when a file plays or finishes playing. So, you could turn on gpio 5 when the file plays, and turn it off on the timeout or videoend that goes from one file to the next.

  Thanks for the quick reply Lynden.  Per your resoponse, that's exactly what I have now.  
  
  What I'd like to see is, instead of turning the light off or on for the duration of the presentation, I'd like the light to blink in 1/2 second intervals until the presentation is over.  Any ideas?
  
  Thanks again...

  We would need to either do a custom script, or customize the autorun from BrightAuthor. One thing we could do is add events to your video when the video file is played. And, then listen for the video events, and each time one occurs, we could change the state of the gpio out. Does this project only have one video?

  Sorry, there is no video.  It's an audio-only, headphone kiosk with four playback tracks.  When the visitor walks up to the Kiosk they have four buttons, each with a placque above with a brief description of the audio track associated with that button.  The buttons each have an LED in them and that LED will be lit until the visitor presses the button.  Once the button is pressed, I want the LED to blink.  
  
  Right now, the way I have it programmed, the button LED turns off when the button is pressed and comes back on when the audio track has finished playing.
