💻 Example Arduino Code (ESP32 + LED Button)

C/C++
#include <WiFi.h>
#include <BlynkSimpleEsp32.h>

char auth[] = "YourAuthToken";
char ssid[] = "YourWiFi";
char pass[] = "YourPassword";

#define LED_PIN 2

BLYNK_WRITE(V1) {
  int pinValue = param.asInt();
  digitalWrite(LED_PIN, pinValue);
}

void setup() {
  pinMode(LED_PIN, OUTPUT);
  Serial.begin(115200);
  Blynk.begin(auth, ssid, pass);
}

void loop() {
  Blynk.run();
}
