/*
This is 8 of 37 Sensors Tutorial code
NOTE: Please replace $ sign with open and close Angle brackets in the code below, because YOUTUBE won't let me include angle brackets in video's Description.

#include $LiquidCrystal_I2C.h$ //In this line Please replace $ sign with open and close Angle brackets

//connections SDA--A4 and SCL--A5
//initialize the liquid crystal library
//the first parameter is the I2C address
//the second parameter is how many rows are on your screen
//the third parameter is how many columns are on your screen

int SensorPin = 8;
int ledPin = LED_BUILTIN;
int state = 0;

void setup() {

lcd.init(); //initialize lcd screen
lcd.backlight(); // turn on the backlight
pinMode(ledPin, OUTPUT);
pinMode(SensorPin, INPUT);
}

void loop() {
delay(100);
state = digitalRead(SensorPin);
lcd.clear();
lcd.setCursor(0, 0); //write on the top row
lcd.print("Sensor Data: ");
lcd.print(state);


if (state == LOW) {
digitalWrite(ledPin, LOW);

} else {
digitalWrite(ledPin, HIGH);
lcd.setCursor(0, 1); //write on the bottom row
lcd.print("Line Found!!");
}
