LINE FOLLOWER

Tasks:

1. Write the program to control the robot follow the line ( actually above the edge between black and white area ). Some programming hints you can find in [@lst:340_Line_Follower] :

#include "RobotMovingFunctions.h"
const int LIGHT_SENSOR_PIN = A0;
const int SURFACE_BRIGHTNESS_REFERENCE = 400;

void setup()
{
  setIOpins();
  pinMode(LIGHT_SENSOR_PIN , INPUT);
}

void loop()
{
  int light_sensor_value = analogRead(LIGHT_SENSOR_PIN );
  if ( light_sensor_value < treshold_value )
  {
    // do this if robot is over the black line

  }
  else
  {
    // do this if robot is over white area
     
  }
}

: Line Follower. {#lst:340_Line_Follower}

Questions:

1. What is the program function to get the light_sensor_value?
2. Determine the movements of the robot if the robot is over the black area and if the robot is over the white area.
