Important Considerations and Best Practices

• Mounting Height: Ensure the sensor is mounted at an optimal height (0.1 cm - 1.5 cm) above the line for accurate detection.
• Surface and Line Color: The sensor works best with high-contrast lines (e.g., black line on a white surface).
• Ambient Light: Minimize ambient light interference by shielding the sensor if necessary.

4. Example Code for Arduino UNO

/*
 * Manta Line Sensor Example Code
 * This code reads the output from the Manta Line Sensor and
 * prints the sensor state to the Serial Monitor.
 */

const int sensorPin = 2; // Pin connected to OUT pin of the sensor
int sensorState = 0;     // Variable to store the sensor state

void setup() {
  pinMode(sensorPin, INPUT); // Set sensor pin as input
  Serial.begin(9600);        // Initialize serial communication
}

void loop() {
  sensorState = digitalRead(sensorPin); // Read the sensor state

  if (sensorState == HIGH) {
    Serial.println("Line detected"); // Print message if line is detected
  } else {
    Serial.println("No line detected"); // Print message if no line is detected
  }

  delay(100); // Small delay to avoid flooding the serial monitor
}

5. Troubleshooting and FAQs

Common Issues Users Might Face

1. No Line Detection:

   • Solution: Ensure the sensor is at the correct height above the line. Check the power supply and connections.

2. False Positives:

   • Solution: Reduce ambient light interference. Ensure the line and surface have high contrast.

3. Intermittent Detection:

   • Solution: Stabilize the sensor mounting. Check for loose connections.

FAQs
