This code must be uploaded to the ESP-01 by the help of a Serial to USB Converter. Code can also be found in File-> Example-> Blynk -> Boards_WiFi -> ESP8266_Standalone
#define BLYNK_PRINT Serial

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "YourAuthToken";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "YourNetworkName";
char pass[] = "YourPassword";

void setup()
{
  // Debug console
  Serial.begin(9600);

  Blynk.begin(auth, ssid, pass);
}
