SunFounder 3in1 Kit
Code
Note:
• You can open the file 3.3.detect_the_obstacle.ino under the path of 3in1-kit\learning_project\
3.3.detect_the_obstacle.
• Or copy this code into Arduino IDE.
When the IR obstacle avoidance module detects something blocking in front of it, [0] will appear on the serial monitor,
otherwise [1] will be displayed.
4.3.5 3.4 Detect the Line
The line tracking module is used to detect whether there are black areas on the ground, such as black lines pasted with
electrical tape.
One of its LEDs emits appropriate infrared light to the ground, and the black surface has a relatively strong ability to
absorb light and a weaker reflection ability. White surfaces are the opposite. If it detects reflected light, it means the
ground is currently white. If not detected, it means black.
That’s how it works.
