: It defines the BlynkWifi class, which handles the connection to a local network using provided SSID and password credentials.
The BlynkSimpleEsp8266.h file acts as the primary interface for ESP8266-based boards (like the NodeMCU or Wemos D1 Mini) to communicate with Blynk servers over Wi-Fi. It simplifies complex networking tasks into a few high-level commands, allowing developers to focus on hardware logic rather than low-level TCP/IP protocols. Core Functionality blynksimpleesp8266 h
