14.3 Warning Lights or Breathing Lights in Other Projects
● When your project needs to use LED lights for warning lights or breathing lights, you don’t need to
rewrite the above code, just copy robotLight.py in the robot program server folder to the same In the folder,
then use the following code to use the warning light or breathing light:
import robotLight
