Lesson 2: Obstacle Avoidance Robot Car
In this lesson, you must complete lesson 1 before you continue on with this lesson. we
use the ultrasonic module to “see” obstacle and measure the distance. If the distance
is less than pre-defined threshold value, the car will turn around from the obstacle
automatically.
