## Phidget Digital Output.lvlib:DigitalOutputSetLEDForwardVoltage.vi

The `DigitalOutputLEDForwardVoltage` 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 `DigitalOutputLEDForwardVoltage` 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.

| Device In Device # Identification

| error in (no error) error in can accept error information wired from VIs previously called.

| status status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

| code code is the error or warning code. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

| source source describes the origin of the error or warning. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
