 How to setup
 You must be using a BBC Microbit microcontroller that has
 been flashed with the firmware from @sandeepmistry

 More info:
 https://gobot.io/documentation/platforms/microbit/#how-to-install

 This example uses the Microbit's built-in LED matrix.
 You run the Go program on your computer and communicate
 wirelessly with the Microbit.

 How to run
 Pass the Bluetooth name or address as first param:

	go run examples/microbit_led.go "BBC micro:bit [yowza]"

 NOTE: sudo is required to use BLE in Linux
