Arduino Self-Driving Car Lesson 7: Following a Lane

The video tutorial explains how to use infrared sensors with Arduino to enable autonomous vehicle lane detection. It covers the differences between digital and analog readings, circuit setup, and code implementation. The tutorial also includes testing and calibration of sensors, as well as programming vehicle behavior based on sensor inputs. The goal is to create a vehicle that can autonomously navigate a track by detecting lane lines using infrared sensors.
