Circuit Documentation
Summary
This circuit is designed to control four "Motor amarillo motorreductor hobby" motors using an "ESP32 - CAM" microcontroller and an "L298N DC motor driver". The motors are powered by a "12v Battery". The ESP32 - CAM is responsible for sending control signals to the L298N driver, which in turn controls the direction and speed of the motors. The battery provides the necessary power for both the motors and the motor driver, while the ESP32 - CAM is powered by the 5V output from the L298N driver.

Documented Code
No code has been provided for the ESP32 - CAM microcontroller. The expected code should handle the initialization of the GPIO pins connected to the L298N motor driver and manage the PWM signals to control the speed and direction of the motors.
