Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an ESP32 microcontroller, two 12V geared motors, two two-channel 5V relays, and a 12V power supply. The ESP32 controls the relays, which in turn control the motors. The power supply provides the necessary voltage for the motors and relays.
