This is a solution for Adafruit OLED display (SSD1306) not working when connected to Nodemcu/ Arduino/ ESP8266 via I2C.

Have you tried connecting your Arduino/ESP8266/Nodemcu/Wemos or any other device to I2C protocol OLED display and installing the example code available in Adafruit SS1306 library only to realise that the screen remain blank and doesn't show example graphics that are visible on other youtube tutorials?
I experienced the same thing and after struggling to find an answer for couple of hours, this is the solution I have come up with. It worked for me and hopefully this short tutorial will solve your problem as well.
