LED Building Block

The LED building block represents a single Light-Emitting Diode ("LED") on a controller.

An LED building block has one ON/OFF input and one ON/OFF output. When the input value changes, the building block adjusts the LED based on the block's settings.

To configure an LED building block, select the actions that the block should perform when its input turns ON and when it turns OFF. The available actions are:

Turn LED ON

Turn LED OFF

Do Nothing

In the example to the right, the Building block will turn the LED on when the building block turns ON, and will turn the LED off when the building block turns OFF.

Not all controller LEDs are controllable with the LED building block. Some devices use a custom interface that is incompatible with ControllerMate.
