Check Your Understanding:
1. How does the Line Tracking Sensor work?
It picks up solar radiation developed by the infrared LED
It picks up reflected light developed by the infrared light sensor
The infrared light sensor illuminates a surface and the infrared LED measures the reflected light
The infrared LED illuminates a surface and the infrared light sensor measures the reflected light
2. Light intensity readings from the Line Tracking Sensor range from:
0 to 100
0 to 1000
0 to 4095
-100 to +100
3. The Line Tracking Sensor provides high light intensity readings for light surfaces and low intensity reading for dark surfaces.
True
False
4. The Line Tracking Sensor is not affected by ambient light.
True
False
