// ver.0 - small changes by Nicu FLORICA (niq_ro), 31-May_2019
// ver.1 - add DHT sensor for temperature and humidity
// ver.1.a - change at add text to be more easy to change
// ver.2 - change temperature to be as float
// ver.3 - add increase/decrease brightness for day/night & verify NTP time at every hour + work as clock without wifi network (reconnect)
// ver.3d - add led for indicate syncronisation with NTP server
// ver.3e - change brightness using photoresistor (at NodeMCU: +3V3----LDR----A0(ADC)----|==10k==|------GND )
// ver.31 - verify quick the light level

//#define DHTTYPE DHT11 // DHT 11
#define DHTTYPE DHT22 // DHT 22 (AM2302)
//#define DHTTYPE DHT21 // DHT 21 (AM2301)
// Connect pin 1 (on the left) of the sensor to +5V
// NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1
// to 3.3V instead of 5V!
// Connect pin 2 of the sensor to whatever your DHTPIN is
// Connect pin 4 (on the right) of the sensor to GROUND
// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor
// Initialize DHT sensor for normal 16mhz Arduino
//DHT dht(DHTPIN, DHTTYPE);
// NOTE: For working with a faster chip, like an Arduino Due or Teensy, you
// might need to increase the threshold for cycle counts considered a 1 or 0.
// You can do this by passing a 3rd parameter for this threshold. It's a bit
// of fiddling to find the right value, but in general the faster the CPU the
// higher the value. The default for a 16mhz AVR is a value of 6. For an
// Arduino Due that runs at 84mhz a value of 30 works.
