Code For Led brightness controll using Slider

 Code for Led brightness controll using Slider of Blynk app with NodeMCU esp8266


#define BLYNK_PRINT Serial

// You should get Auth Token in the Blynk App.

// Go to the Project Settings (nut icon).

char auth[] = "cdvbhkl7swRm-cJy5Tu_F2J17j-pIuKr";


// Your WiFi credentials.

// Set password to "" for open networks.

char ssid[] = "Name";

  // You can also use:

  // String i = param.asStr();

  // double d = param.asDouble();

  analogWrite(D1,pinValue);

  Blynk.virtualWrite(V1, pinValue);

  Blynk.begin(auth, ssid, pass);

  // You can also specify server:

  //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);

  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
