Circuit Documentation

Summary

The circuit in question appears to be designed for a mobile platform, possibly a robot or a vehicle, which utilizes a GPS module for positioning, a metal detector for object detection, and an ESP32-CAM for wireless communication and possibly image capture. The circuit is powered by a 12V battery and includes a rocker switch for power control. The L298N motor driver is used to control the gearmotors for the wheels, allowing for bidirectional movement. The ESP32-CAM also interfaces with the GPS module and the metal detector for data processing and decision-making.
