Line Tracking Module (Arduino Compatible)

Detect the "lightness" of an object using this Line Tracking Module. Just 3 pins: Power, Ground and signal. The signal pin is 5V when over a black surface and 0V when over a white surface. Good for detecting the difference between a black line on a white surface for line tracking as well as other applications.

Specifications:

• Digital Line Tracking Module
• Detects white or black surfaces
• Pinout:
• VCC: 5V
• GND: 0V
• OUT:
• 5V when over a white surface
• 0V when over a black surface

To detect all colors, check out our Color Sensor that can detect a full spectrum of colors.

Sample Arduino Code:

int Led = 13 ;// define LED Interface
int buttonpin = 3; // define tracing sensor interface
int val ;// define numeric variables val
void setup ()
{
    pinMode (Led, OUTPUT) ;/ / define LED as output interface
    pinMode (buttonpin, INPUT) ;/ / define tracing sensor output interface
}
void loop ()
{
    val = digitalRead (buttonpin) ;/ / digital interface will be assigned a value of 3 to read val
    if (val == HIGH) / / When the sensor detects a tracking signal, LED flashes
    {
        digitalWrite (Led, HIGH);
    }
    else
    {
        digitalWrite (Led, LOW);
    }
}
