Circuit Documentation
Summary of the Circuit
This circuit consists of an ESP32-WROOM-32UE microcontroller, a green two-pin LED, and a PIR (Passive Infrared) sensor. The ESP32 microcontroller serves as the central processing unit, controlling the LED and receiving signals from the PIR sensor. The LED is used as an indicator, and the PIR sensor is used to detect motion within its field of view. The circuit is designed to light up the LED when motion is detected by the PIR sensor.

Documented Code
Since no code was provided, this section is left blank. The expected behavior, based on the wiring, would be for the ESP32 to monitor the signal from the PIR sensor and turn on the LED when motion is detected. The code would involve setting up the GPIO pins, configuring the PIR sensor input, and writing the logic for LED control.
