    Each block represents a different action, such as “show a heart” or “play a
                      sound,” and can be easily connected to build a program.

                      Block-based  programming  helps  you  quickly  see  the  results  of  their  code,

                      making it a fun way to learn programming and bring the micro:bit to life.

                      Overview

                      In  this  project  different  types  of  icons  will
                      print on display matrix of micro:bit. Micro:bit

                      having 5 × 5 display matrix where total 25 Leds
                      are placed so using this display we can print n

                      numbers of icons. Few icons are already there
                      in the block code so we can directly use those
                      icons as well as we can make our own icons.

                      The Micro:bit LED screen has 25 red LED lights

                      arranged in a 5 × 5 grid (5 LEDs across by 5
                      LEDs down).

                      We can use (x, y) coordinates to specify a particular LED in the grid; where x is
                      the horizontal position (0,1,2,3,4) and y is the vertical position (0, 1, 2, 3, 4).
