Getting the SSD1306 OLED Display to work on the ESP8266 via D1 Mini.

First, open your arduino IDE, and go to preferences.
In the "Additional Boards Manager URLs" field, enter "http://arduino.esp8266.com/stable/package_esp8266com_index.json"
press "okay"

Now go to to "Tools->Board->Boards Manager"
Find "esp8266" by "ESP8266 Community", and install it. This installs the toolchain and libraries needed.

Now under "Board", select your esp8266 board, in this case, the d1 mini.

/*********************************************************************
This is an example for our Monochrome OLEDs based on SSD1306 drivers

  Pick one up today in the adafruit shop!
  ------> http://www.adafruit.com/category/63_98

This example is for a 128x64 size display using I2C to communicate
3 pins are required to interface (2 I2C and one reset)

Adafruit invests time and resources providing this open source code,

Getting an SSD1306 i2c LCD display to work on an arduino UNO.

First, you need to hook up the 4-pin lcd device up to your arduino:

GND goes to GND
VDD goes to 5V
SCK goes to A5
SDA goes to A4

Next, identify the i2c device address of your lcd panel. Run the following sketch with the serial monitor open, and note the 8bit address that it returns:

  uint8_t pin = 0; //this is also the ID
  uint16_t potResolution = 0;
  
  public:
  Pot(uint8_t pin_, uint16_t potResolution_) {
    pin = pin_;
