Project 17 Line Tracking Sensor

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

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

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

5. 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.
