## Phidget Digital Output.lvlib:DigitalOutputSetLEDForwardVoltage.vi

The `LEDForwardVoltage` is the voltage that will be available to your LED.

- Reference the data sheet of the LED you are using before setting this value. Choose the `LEDForwardVoltage` that is closest to the forward voltage specified in the data sheet.
- This forward voltage is shared for all channels on this device. Setting the LEDForwardVoltage on any channel will set the LEDForwardVoltage for all channels on the device.
