ESP8266 with DHT11 and OLED

My second trying with Arduino and show temperature data on a mini OLED display.
Its display a test text and after that its will the data.

Parts:

• Adafruit ESP8266 as NodeMCU 1.0 (ESP-12E modul),
• 0.96″ 128x64 mini OLED display (I use white color for that project),
• DHT11 temperature and humidity sensor
• Jumper cables.

You can see a picture from the full setup here:

Arduino Modules:

• Adafruit_SSD1306,
• Adafruit_GFX,
• DHT

It is the next step on my first project as

Connection:

• Display GND to ESP G
• Display VCC to ESP 3V
• Display SCL to ESP D1 as GPIO 1
• Display SDA to ESP D2 as GPIO 2
• DHT + to ESP 3V (Can be the same as where the display VCC)
• DHT - to ESP G (Can be the same as where the display GND)
• DHT OUT to ESO D5 as GPIO 14

Coding in Arduino IDE 1.8.19
I made this code from sources of the internet. There is no copyright, use it as you want.
