Arduino IDE can t find ESP8266WiFi h file

0 votes

I have been using NODEMCU ESP8266WiFi with Arduino IDE

When I run this code:

#include <ESP8266WiFi.h> 
#include <BlynkSimpleEsp8266.h> 
char auth[] = "YourAuthToken"; 
char ssid[] = "YourNetworkName"; 
char pass[] = "YourPassword"; 

void setup(){ 
    Serial.begin(9600); 
    Blynk.begin(auth, ssid, pass); 
}
void loop() 
{ 
    Blynk.run(); 
}


I get the following error:

fatal error: ESP8266WiFi.h: No such file or directory 

            #include <ESP8266WiFi.h> ^ 

compilation terminated. 

exit status 1 
Error compiling for board Arduino/Genuino Uno.

Customisation and selection of the correct card is essential while you are programming the NODEMCU card with the Arduino IDE. 

Open Arduino IDE and go to files and click on the preference in the Arduino IDE.

Add the following link to the Additional Manager URLS section: "http://arduino.esp8266.com/stable/package_esp8266com_index.json" and press the

OK button.
 

Then click Tools> Board Manager. Type "ESP8266" in the text box to search and install the ESP8266 software for Arduino IDE.

You will be successful when you try to program again by selecting the NodeMCU card after these operations. I hope I could help you.
