-**Central**
+This example can be used with two Bluetooth® supported Arduino boards, one with a button, and the other with an LED. When the button is pressed, it will advertise a corresponding value (high/low), which will be received by the board with an LED.

+#### Central
 
   This example scans for Bluetooth Low Energy peripherals with a specific UUID (in this case another Arduino board), connects to it, and lets you control the built-in LED with a button connected to pin 4.
