You can turn GPIO outputs on/off quickly when interacting with Media or Event States using the **Pause** command (for example, to flash buttons) in BrightSign Author.

When using GPIO output(s) the GPIO pin in use must be configured as an output pin. To do this go to **Presentation Settings > Interactive > Connectors > GPIO Configuration** and select **Output** for the GPIO pin connected to the LED.

# Media State

1. Create an [Advanced presentation](docId:0Vm0UTpL2j8dss-DFNhMo). 
2. Select the Media State where you want the GPIO pulse to occur.
3. In **State Properties**, go to **Advanced**.
4. Use the "+" to add three **Entry Commands** or three **Exit Commands** (depending on when you want the pulse to be triggered). 
5. Set the first **Command** to **GPIO** and the **Parameters** to **On**. Enter the GPIO pin that's connected to the LED. 
6. Set the second **Command **to **Other** and the **Parameters**  to **Pause**. Enter a short pause (in milliseconds).
7. Set the third **Command** to **GPIO** and the **Parameters** to **Off**. Select the GPIO pin used in step 5.

1. Create an [Advanced presentation](docId:0Vm0UTpL2j8dss-DFNhMo). 
2. Select the media state where you want the GPIO pulse to occur.
3. In **Event Properties**, select the **Advanced** tab.
4. Use **Add Command** to add three commands
5. Set the first **Command** to **GPIO** and the **Parameters** to **On**. Enter the GPIO pin that's connected to the LED. 
6. Set the second **Command** to **Other** and the **Parameters** to **Pause**. Enter a short pause (in milliseconds).
7. Set the third **Command** to **GPIO** and the **Parameters** to **Off**. Select the GPIO pin used in step 5.
