4. Working Principle
The dual-path line-following sensor detects black lines on the ground using photoelectric sensors and outputs corresponding signals. Its operation is as follows:
-
Power connection : Connect to power via GND and VCC, supports DC 5V.
-
Signal output : The sensor outputs signals to indicate whether black lines have been detected by reflecting infrared light.
