Stap 6: De ESP8266 voorbereiden op Programing
De Arduino IDE downloaden als u niet reeds hebt: https://www.arduino.cc/en/Main/Software
Nu moet u de ESP8266 knooppunt MCU 12E toevoegen als een selecteerbaar board binnen de Arduino IDE.
Volg de instructies die gedetailleerde hier: http://www.whatimade.today/esp8266-easiest-way-to-...
Nu je alle opties van de ESP moet als selecteerbaar planken wanneer u klikt op Tools -> Boards in de IDE
Kopieer en plak deze code in de Arduino IDE:
