Indeed many changes to start off optimistically:]

Pretty much just learned how to use the board, the components, wiring of things and how to use a breadboard.

Also I have been really frustrated to learn that arduino ides and bunch of other things work absolutlely terrible under linux and not only. It even works buggy ways within Windows (i also tried legacy versions and achieved the same conclusion).

Anyways, not really much to detail other than my learning process.

+// Example testing sketch for various DHT humidity/temperature sensors
+// Written by ladyada, public domain
+
+// REQUIRES the following Arduino libraries:
+// - DHT Sensor Library: https://github.com/adafruit/DHT-sensor-library
+// - Adafruit Unified Sensor Lib: https://github.com/adafruit/Adafruit_Sensor
+
+#include "DHT.h"
+
+#define DHTPIN 4     // Digital pin connected to the DHT sensor
+// Feather HUZZAH ESP8266 note: use pins 3, 4, 5, 12, 13 or 14 --
+// Pin 15 can work but DHT must be disconnected during program upload.
+
+// Uncomment whatever type you're using!
+//#define DHTTYPE DHT11   // DHT 11
+#define DHTTYPE DHT11   // DHT 22  (AM2302), AM2321
+//#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 3 (on the right) of the sensor to GROUND (if your sensor has 3 pins)
+// Connect pin 4 (on the right) of the sensor to GROUND and leave the pin 3 EMPTY (if your sensor has 4 pins)
+// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor
+
+// Initialize DHT sensor.
+// Note that older versions of this library took an optional third parameter to
+// tweak the timings for faster processors.  This parameter is no longer needed
+// as the current DHT reading algorithm adjusts itself to work on faster procs.
