//Created by Barbu Vulc!
//Libraries needed for code:
#include <Arduino_FreeRTOS.h>
#include <LiquidCrystal.h>
//Create the 'lcd' object:
LiquidCrystal lcd(7, 8, 9, 10, 11, 12);

//Define variables for photoresistor:
const int sensorMin = 0;   //Sensor minimum...
const int sensorMax = 500; //Sensor maximum...

void setup() {
  //LCD initialization:
  lcd.begin(16, 2);
  //Task initialization:
  xTaskCreate(Task, "Photoresistor & LCD", 100, NULL, 0, NULL);
}

//The task for photoresistor & LCD:
static void Task(void* pvParameters) {
  while (1) {
    lcd.setCursor(0, 0);
    //The photoresistor variable...
    int ldr = analogRead(A0);
    int range = map(ldr, sensorMin, sensorMax, 0, 3);
    lcd.println(range);  lcd.println("lux");
    vTaskDelay(500 / portTICK_PERIOD_MS);
    lcd.clear();
  }
}

//We don't need to use 'loop' function here!
void loop() {}
