This project detects motion using a Mini PIR sensor and triggers the Arduino's built-in LED. When movement is detected, the LED turns on and a notification is printed to the Serial Monitor. Allow a brief warm-up period after powering on for the sensor to stabilize.

This project detects human motion using a Mini PIR motion sensor. When motion is detected, the ESP32 turns on the onboard LED (GPIO 2) and logs a message to the Serial Monitor. Powering the sensor with 3.3V ensures safe signal levels for the ESP32 input.
