Candelabra Microbit remote controller
A second Microbit is used as the remote controller to select the display pattern on the Candelabra.
However, if this second Microbit is not available the main control unit will still function witout it.
It will just be required that the A and B buttons on the main controller be used.

On start set the radio group and the name that must match with the main controller to enable BLE pairing.
The on buttons each send a different number to the main unit which replicate the buttons options on the main controller.
On radio received displays the text that represents the pattern selected.
