2) Programming Thinking
1 At first, use a ultrasonic module to measure the distance between the micro:bit car and an obstacle
ahead.
2 When the measured distance is less than 10cm, the micro:bit car stops for 0.2 second, then turns left for
0.5 second and then goes forward. If the measured distance is greater than or equal to 10cm, the micro:bit car
will directly go forward.
