SMARS DEMO 1:

#include <AFMotor.h>

// SMARS Demo 1 with line sensor
// This sketch makes the robot move inside a delimitated area
// (you can make a perimeter with insulating tape)

AF_DCMotor motorL(1); // left motor
AF_DCMotor motorR(2); // right motor

// declare variables

int lineNumber; // defines the variable where it will
// store the line sensor value

void setup() {
Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
// changes the following values to make the robot drive as
// straight as possible

motorL.setSpeed(200); // sets motorL speed
motorR.setSpeed(200); // sets motorR speed
motorL.run(RELEASE); // turns motorL off
motorR.run(RELEASE); // turns motorR off
}

void loop() {
lineNumber = analogRead(A0); // reads the sensor value from pin A0
// and stores it in the variable lineNumber
while (lineNumber < 800) // (WIT) repeats the following part
// of code until the light sensor will find a darker zone
{
motorL.run(FORWARD); // forward
motorR.run(FORWARD);
lineNumber = analogRead(A0); // reads the sensor value from pin A0
// and stores it in the variable lineNumber
Serial.print("linenumber: ");

}

// the following operations will make the robot goes backward for
// 1 second and turns left for 0.15 second

motorL.run(RELEASE); // stop
motorR.run(RELEASE);
