✅ ❌ Do NOT use it for the new Blynk IoT platform. 3. Basic Code Structure Here is a minimal working example for connecting an ESP8266 to Blynk Legacy:

// Connect to Blynk cloud server (default: blynk-cloud.com:8080) Blynk.config(auth, ssid, pass); // or simply: Blynk.begin(auth, ssid, pass); blynksimpleesp8266 h

#define BLYNK_PRINT Serial // Enable debug output to Serial Monitor #include <ESP8266WiFi.h> // ESP8266's Wi-Fi library #include <BlynkSimpleEsp8266.h> // Blynk + ESP8266 magic ✅ ❌ Do NOT use it for the new Blynk IoT platform

void sendSensor() float h = dht.readHumidity(); float t = dht.readTemperature(); Blynk.virtualWrite(V5, t); Blynk.virtualWrite(V6, h); // or simply: Blynk.begin(auth

#include <DHT.h> DHT dht(D1, DHT11); void setup() dht.begin(); timer.setInterval(2000L, sendSensor); // BlynkTimer library

// Optional: Connect to a custom local server // Blynk.begin(auth, ssid, pass, "192.168.1.100", 8080);

// Your credentials from the Blynk app char auth[] = "YourAuthTokenHere"; char ssid[] = "YourWiFiSSID"; char pass[] = "YourWiFiPassword";
