Toto je zatial len priebezne robena zbierka prikladov

• 
  Prvý program...
• 
  ...bude vyzerať v simulátore takto.

JavascriptPythonC++

    
basic.showIcon(IconNames.Heart)

from microbit import *

display.show(Image.HEART)

 #include "MicroBit.h"

 MicroBit uBit;
 MicroBitImage Heart("0,1,0,1,0\n
                      1,0,1,0,1\n
