How to Use 3 Channel Path Tracing Module
Connect VCC to your 5V rail and GND to ground, then wire the L, C and R output pins to your microcontroller’s digital inputs. Adjust each channel’s potentiometer while observing output LEDs or serial readings to set the ideal threshold for your surface contrast. Use simple digitalRead() logic or interrupt routines to respond when a sensor detects or loses the line.

Frequently Asked Questions
How do I connect the module to an Arduino?
Wire VCC to the Arduino’s 5V pin, GND to GND, and the L, C, R outputs to three digital input pins. In your sketch, use digitalRead() on those pins to detect high/low states when the sensors cross a line.
How can I adjust the detection sensitivity?
Each channel has a small potentiometer next to the sensor. Turn the screw clockwise to increase sensitivity (detect lighter lines) or counterclockwise to decrease it, then test on your surface until the output toggles reliably.
Will ambient light affect the sensors?
The CTRT5000 elements include anti-jamming design to reduce interference from ambient infrared sources. For best results, perform calibration in your operating environment and cover the module from direct sunlight.
