Circuit Documentation
Summary
This circuit integrates an Arduino UNO microcontroller with an L298N DC motor driver to control two hobby motors. Additionally, an HC-SR04 Ultrasonic Sensor is included, likely for distance measurement or obstacle detection. The Arduino UNO is responsible for providing control signals to the L298N driver, which in turn drives the motors. The HC-SR04 sensor is interfaced with the Arduino for input. Power distribution is managed through the 5V and GND connections from the Arduino to both the motor driver and the ultrasonic sensor.
