Use the Pause command to pulse GPIO outputs:

1. Create an Interactive presentation in BrightAuthor.

2. Open the Media State or Event where you want the GPIO pulse to occur.

3. Select the Advanced tab.

4. Use Add Command to add three commands:

   1. Set the first command to GPIO -- On. Enter the GPIO pin connected to the LED (it must be configured as an output pin in File > Presentation Properties > I/O).

   2. Set the second command to Other -- Pause. Enter a short length of time (in milliseconds) to pause.

   3. Set the third command to GPIO -- Off. Select the GPIO pin used in step a.
