+ * Example LED Remote
+ *
+ * This is an example of how to use the RF24 class to control a remote
+ * bank of LED's using buttons on a remote control.
+ *
+ * On the 'remote', connect any number of buttons or switches from
+ * an arduino pin to ground.  Update 'button_pins' to reflect the
+ * pins used.
+ *
+ * On the 'led' board, connect the same number of LED's from an
+ * arduino pin to a resistor to ground.  Update 'led_pins' to reflect
+ * the pins used.  Also connect a separate pin to ground and change
+ * the 'role_pin'.  This tells the sketch it's running on the LED board.
+ *
+ * Every time the buttons change on the remote, the entire state of
+ * buttons is send to the led board, which displays the state.
