The Makerlabvn_I2C_Line_Follower_Sensor library allows you to interface with the Makerlabvn I2C Line Follower Sensor using Arduino. This sensor helps in detecting lines on the ground, which is useful for line-following robots.

1. Open the Arduino IDE.
2. Go to Sketch > Include Library > Manage Libraries....
3. In the Library Manager, search for Makerlabvn_I2C_Line_Follower_Sensor.
4. Click on the library and install it.

Here is a simple example to get you started:

#include "Makerlabvn_I2C_Line_Follower_Sensor.h"

Makerlabvn_I2C_Line_Follower_Sensor LineFollowSensor;

void setup()
{
    Serial.begin(115200);
    LineFollowSensor.setup(0x2A);
}

void loop()
{
    /************ SENSOR *************/
    /*-------------------------------*/
    /* |LEFT| P1 P2 P3 P4 P5 |RIGHT| */
    /*     0b 1  1  1  1  1          */
    /*         0: White;             */
    /*         1: Black              */
    /*-------------------------------*/
    LineFollowSensor.getData();
    
    Serial.print("P1:");
    Serial.print(LineFollowSensor.getValue(0));
    Serial.print(" P2:");
    Serial.print(LineFollowSensor.getValue(1));
    Serial.print(" P3:");
    Serial.print(LineFollowSensor.getValue(2));
    Serial.print(" P4:");
    Serial.print(LineFollowSensor.getValue(3));
    Serial.print(" P5:");
    Serial.print(LineFollowSensor.getValue(4));

    Serial.print(" data:");
    Serial.println(LineFollowSensor.getValue(), BIN);
    
    
    delay(50);
}

Initializes the sensor with the specified I2C address.

• Parameters:
  • address (uint8_t): The I2C address of the sensor. (From 0x2A to 0x2E), setup by Double-Click then Long Press button S1 on the sensor

Reads the sensor data and updates the internal state.

Returns the value of the sensor at the specified position.

• Parameters:

  • position (uint8_t): The position of the sensor (0 to 4).

• Returns:

  • uint8_t: The value of the sensor at the specified position (0 for white, 1 for black).

Returns the combined value of all sensors as a single byte.

• Returns:
  • uint8_t: The combined value of all sensors in binary format.
