Solution: make sur you got the sketch to load to your object.

"fatal error: Adafruit_SSD1306.h: No such file or directory"
install the library from Sketch → Include Library → Manage Libraries: type SSD1306 in the search bar and find it.
|In the list of SSD1306 Libraries, make sure you install the one by Adafruit, not Acrobotic.|
Import this lirary in your sketch via Sketch → Include Libraries → find it in the list!!
"cannot access COM1 / espcomm_open failed"
if you are on a Mac:
New / recent Mac only: make sure you installed this:
Older Mac (Mac OS 10.12.6 or older): make sure you installed this instead:
All Macs: in the Arduino IDE, with your sketch open, go to
Toolsand put your mouse above (don’t click!)
Port:. Then select:
→ In the list of ports, select the one that has "/dev/cu.SLAB_USBtoUART" in the name
if you are on a PC:

Upload complete but nothing on screen
the wifi ssid is invalid: the name of the ssid you are using includes spaces or special characters (like: "my super wifi")*
→ Use a wifi ssid and passwords which are simpler (like: "mysuperwifi")
If you are on a Mac Computer, the adaptator for USB cables (white cable on the picture below) does not work:
→ try changing the usb cable. Some cables don’t work.
