Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes a rain sensor, a 5V relay, a hobby gearmotor with a 48:1 gearbox, two micro switches, and a 9V battery. The circuit is designed to detect rain and activate a relay, which in turn controls the gearmotor. The micro switches are used for additional control or feedback mechanisms.
