     8   How to setup
     9   You must be using a BBC Microbit microcontroller that has
    10   been flashed with the firmware from @sandeepmistry
    11  
    12   More info:
    13   https://gobot.io/documentation/platforms/microbit/#how-to-install
    14  
    15   This example uses the Microbit's built-in LED matrix.
    16   You run the Go program on your computer and communicate
    17   wirelessly with the Microbit.

    19   How to run
    20   Pass the Bluetooth name or address as first param:
    21  
    22  	go run examples/microbit_led.go "BBC micro:bit [yowza]"
    23  
    24   NOTE: sudo is required to use BLE in Linux
