==Version information==
LED component to drive the E-blocks 2 BL0167 LED board.
Provides eight individually addressable LEDs.


There are component macros in flowcode 8 to turn a selected LED on or off, or you can even use macros to turn all LEDs on or off. Make sure the LED component is connected to the correct port in flowcode which corresponds to the port that it’s connected to on your E-blocks 2 upstream board. When selecting an individual LED to turn on or off you are asked for the index value (0-7), which is the large number shown underneath each LED on the E-blocks 2 board.
