This circuit is designed to interface various sensors, actuators, and modules with an Arduino UNO microcontroller and an ESP-8266 Controller. It includes a LIDAR sensor for distance measurement, a GPS module for location tracking, a DC motor driver for controlling motors, a servo motor for precision control, an ESP32-CAM for image capture, voltage regulators for power management, and water level sensors for detecting the presence of water. The circuit is powered by a 12v Battery and uses a 3.3V regulator and a 7805 voltage regulator to provide the necessary voltage levels to the components. Communication between devices is facilitated through digital, analog, and I2C interfaces.
