Circuit Documentation

Summary of the Circuit

This circuit is designed to interface an ESP32 microcontroller with two servo motors, an infrared (IR) sensor, and two DC motors powered by a 9V battery. The ESP32 is used to control the servo motors and read the output from the IR sensor. The DC motors are connected in parallel to the 9V battery.

Documented Code

There is no code provided for the microcontroller. The documentation of the code would typically include a description of the functionality, setup, and main loop, along with any functions or libraries used. Since no code is available, this section cannot be completed. If code becomes available, it should be documented here with comments explaining the purpose and functionality of each section of the code.
