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. When motion is detected, the LED will stay on for a set period of time, and we will manage the timing using the `millis()` function and a counter, without needing to use `delay()`. This way, we’ll create a motion-sensor-based lighting system that doesn’t tie up the ESP32, allowing it to perform other tasks as well. In real-life applications, it can be used for sta
