5.13 Cliff Detection
This project will use the grayscale module to prevent the PiCar-X from falling off a cliff while it is moving freely
around your home. This is an essential project for houses with staircases.
TIPS
The grayscale module will be performing the same operation multiple times. To simplify the program, this project
introduces a function that will return a list variable to the do forever block.
