 ## LEDs
 
-This section of the user manual explains how to control both the onboard orange and RGB and LEDs on the Nicla Sense Env board using the `Arduino_NiclaSenseEnv` library API. The LEDs can be used to provide visual feedback for various operations, such as indicating status, warnings, or sensor errors. This section covers the basic usage of both LEDs, including turning them on, changing colors, and adjusting brightness.
