}Steps to Install ESP8266 NodeMcu In Arduino IDE
Arduino IDE'de ESP8266 NodeMcu Kurulum Adımları- Navigate to File> Preferences in your Arduino IDE.
- As indicated in the picture below, enter http://arduino.esp8266.com/stable/package esp8266com index.json into the “Additional Boards Manager URLs” section. Then press the “OK” button. If you already have the URL for the ESP32 board, separate the Links with a comma.
- Navigate to Tools > Boards Manager.
- Search for ESP8266 and click the “ESP8266 by ESP8266 Community” install button.
- That’s all. Within a few seconds, it will be installed.
Uploading the Code
- Because it includes a built-in programmer, posting the sketch is quite straightforward. Connect the board to your computer. Check that you have the correct board chosen.
- You must also pick the correct Port.
- In the Arduino IDE, click the “Upload” button and wait a few seconds until you get the message “Done uploading.” in the lower left corner.
