the Arduino framework for ESP32 development.

To create an IoT lock screen, you'll need to use a combination of hardware and software. Below is a simple example of how you might implement a basic IoT lock screen using an ESP32, a servo motor (to represent a lock/unlock mechanism), and a web server for control. In this example, we'll use the Arduino framework for ESP32 development.

Please note that this is a simplified example, and you might need to adapt it based on your specific requirements.

Hardware Setup:

Connect the servo motor to the appropriate pin on the ESP32. For example, connect it to GPIO 4.

Make sure your ESP32 is connected to your Wi-Fi network.

#include <WiFi.h>

#include <ESPAsyncWebServer.h>

#include <Servo.h>

const char *ssid = "your-ssid";

const char *password = "your-password";

Servo lockServo; // Create a servo object

const int servoPin = 4; // Pin to which the servo is connected

bool isLocked = false;

AsyncWebServer server(80);

void setup() {

  Serial.begin(115200);

  // Attach the servo to the pin

  lockServo.attach(servoPin);

  // Connect to Wi-Fi

  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {

    delay(1000);

    Serial.println("Connecting to WiFi...");

  }

  Serial.println("Connected to WiFi");

  // Define web server routes

  server.on("/", HTTP_GET, [](AsyncWebServerRequest *request){

    request->send(SPIFFS, "/index.html", String(), false);

  });

  server.on("/lock", HTTP_GET, [](AsyncWebServerRequest *request){

    isLocked = !isLocked;

    controlLock();

    request->send(200, "text/plain", isLocked ? "Locked" : "Unlocked");

  });

  // Serve static files from SPIFFS

  server.serveStatic("/", SPIFFS, "/");

  server.begin();

}

void loop() {

  // Do nothing here for now

}

void controlLock() {

  if (isLocked) {

    lockServo.write(0); // Rotate servo to the locked position

  } else {

    lockServo.write(90); // Rotate servo to the unlocked position

  }

  delay(1000); // Allow time for the servo to move

}
