29.8.3. Reference#
from microbit import *
from matrix import *
matrix = MATRIX()
x, y = 0, 0
while True:
for y in range(8):
for x in range(16):
matrix.set_matrix_draw(x, y)
matrix.set_matrix_clear()
29.8.4. Result#
Each LED lights on from the sequence of left to right and up to down, then they light off after all the LEDs light up.
