Using light sensors course concentrates on how to use light sensors to follow a line. Topics:
• Basics of following line with a single light sensor
• Improving line following performance with two light sensors
• Following a curve
• Calibrating the light sensors
• Putting it all together: finding the line, aligning to the line, following the line, stopping along the line and orienting the robot after stopping
• How to stop based on distance, time, touch sensor trigger or detecting a cross line
• Stress testing the light sensor program
