Summary

This circuit is designed to interface a rain sensor with an Arduino 101 microcontroller. The circuit also includes an LED indicator that lights up based on the sensor's output. The rain sensor detects the presence of rain and sends a digital signal to the Arduino, which then processes this signal and controls the LED accordingly.
