Circuit Documentation
Summary
This circuit is designed to control a 12V geared motor using an Arduino Nano microcontroller and an L298N DC motor driver. The motor's operation is influenced by two FC-51 IR sensors, which likely serve as input devices to trigger motor actions. The circuit is powered by a 12V 5A power supply, which provides the necessary voltage to the motor driver and indirectly to the other components through voltage regulation on the Arduino Nano.
