Very nice experiment set. The OLED display has 2 colors: yellow and blue. the top 15 rows of the display is all yellow, the rest is in blue. the colour cannot be changed. The DHT11 sensor has a 2 degC offset. This is a commonly known issue for thisbtype of sensor. For better accuracy use a DHT22. The usb cable that came with it does not fit the Nodemcu.
