## 1. Introduction

This Line Tracking Sensor can detect white lines in black and black lines in white. The single line-tracking signal provides a stable output signal TTL for a more accurate and more stable line.

Multi-channel option can be easily achieved by installing required line-tracking robot sensors.

## 2. Specification

- Power supply: +5V
- Operating current: <10mA
- Operating temperature range: 0°C ~ + 50°C
- Output interface: 3-PIN (1 - signal ; 2 - power ; 3 - power supply negative)
- Output Level: TTL level

## 4. Sample Code

Download code: [Code](./Code.7z)

```
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  Serial.println(digitalRead(3)); // print the data from the sensor
  delay(500);
}
```

## 5. Example Result

Done uploading the code to board, open the serial monitor and set the baud rate as 9600, then you can see the data from the sensor. Shown below.
