Summary of the Circuit
This circuit is designed to control a DC motor using an Arduino UNO microcontroller and an L298N DC motor driver. The Arduino UNO is responsible for providing control signals to the L298N driver, which in turn drives the Gearmotor DC Wheels Right. A 9V battery is used to power the motor driver, which also receives a regulated 5V from the Arduino for logic operations.
