How to Build an Ultrasonic Following Robot?

Overview
In the previous project, we have introduced how to build an obstacle following robot.
This project we use an ultrasonic module combined with micro:bit robot shield to build an ultrasonic obstacle
following robot.
How does it work?
The principle is very simple. We will use an ultrasonic module to measure the distance between the micro:bit
robot and an obstacle ahead. Then control the running state of micro:bit robot car according to the measured
distance.
