This page / section pertains to **BrightAuthor Classic**, our legacy app. **BrightSign Author **is our latest app for managing content and players.

Development of BrightAuthor Classic has largely ceased and the app will eventually be deprecated and replaced with BrightSign Author.
:::

Use the **Pause** command to pulse GPIO outputs:

1. Create an Interactive presentation.
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 4.1.
