The two infrared obstacle detector sensors on the micro:bit mini robot car can used to detect an obstacle ahead.
 If the infrared sensors on both side do not detect an obstacle, the LED matrix will show a big heart image.
 If the infrared sensors on both side detect an obstacle, the LED matrix will show a small heart image.
 If the left infrared sensor detects an obstacle, but the right sensor doesn't, the left column of LED matrix will
light up.
 If the right infrared sensor detects an obstacle, but the left sensor doesn't, the right column of LED matrix
