/*  05.010 - Grove LED module
 *   
   This sketch demonstrates how to use the Grove LED kit.

   This module contains a header in which you can attach an LED. Take care
   to connect the anode (long pin) of the LED into the socket marked with "+".
   The cathode should go to the socket marked with "-".

   You can use a Phillips screwdriver to adjust the brightens by turning the 
   on-board potentiometer.
