Automatic Lighting with the ESP32 PIR Motion Sensor

In this project, we will use the HC-SR501 PIR motion sensor to detect when someone enters the room and automatically turn on the LED. We will track how long the LED stays on using `millis()`; each HIGH reading from the sensor will update the last motion time, and the LED will turn off at least 10 seconds after the last HIGH reading. The current code also waits 50 ms in each loop with `delay(50)`, so the application loop is not fully non-blocking. In real-life applications, it can be used for sta
