If you are using an ESP8266 as a Wi-Fi shield for an Arduino Uno, use #include instead of the standard standalone header . #include "BlynkSimpleEsp8266.h" - IDE 1.x - Arduino Forum

This is where the magic happens. The BLYNK_WRITE(V0) function is a special Blynk construct. It is automatically called whenever the widget linked to Virtual Pin V0 on your Blynk dashboard changes state (e.g., you press a button). The param.asInt() function retrieves the new value, and we use it to turn the LED on or off.
Once you've successfully installed the Blynk library, you can create your first IoT project. Here's a simple example that controls an LED connected to your ESP8266 using the Blynk mobile app. in the Arduino Library Manager to get the
The master repository and official releases are hosted on GitHub:
Installing the Blynk library from a ZIP file requires several methodical steps. This manual installation method is particularly useful when you need to ensure complete control over the installation process or when the Library Manager isn't working as expected.
Always download the library from official, verified sources to avoid malware or corrupted code. The BLYNK_WRITE(V0) function is a special Blynk construct
