Welcome to Tiny:bit Robot Car repository

Learning goals:

In this lesson, we will make a very simple micro:bit game. When we press the A button, the micro:bit dot matrix will display an arrow pointing to the A button; when we press the B button, the micro:bit will display an arrow pointing to the B button; if no button is pressed, the micro:bit It shows a heart.

Code：

from microbit import *

while True:

    if button_a.is_pressed():

        display.show(Image.ARROW_W)
