8.6.2 Infrared Obstacle Avoiding Car
1) Description
In the previous project, we have combined sensor and micro:bit car shield to build a specific function car.
Now, we use an infrared obstacle detector module and motor driving circuit on the micro:bit car shield to build
an infrared obstacle avoiding car.
How does it work?
We have introduced the principle of infrared obstacle detector module before. We can make use of two infrared
obstacle detector modules integrated on the car shield to detect whether have obstacles on the both sides of
micro:bit car. Thus control the car’s running state according to the testing interface.
