Circuit Documentation

Summary

This circuit integrates various components including sensors, a microcontroller, a motor driver, and a display module to perform a set of tasks that likely involve motion control and data acquisition. The Arduino UNO serves as the central processing unit, interfacing with an IR sensor, an RFID module, a DC motor driver, an ultrasonic distance sensor, and an LCD display. The circuit is powered by a 12V battery, and a rocker switch is used to control the power supply. The motor driver controls two DC Mini Metal Gear Motors based on signals from the Arduino UNO.
