3. Motor Driver Module (L293D or L298N)
A motor driver module is required because Arduino cannot directly supply enough current to run DC motors. The L293D or L298N motor driver acts as a bridge between Arduino and motors, enabling direction and speed control. It uses an H-Bridge circuit to allow motors to run forward, backward, or stop. In this project, Arduino sends control signals to the driver, which then powers the DC motors accordingly. Without the motor driver, the motors would not function properly. This component ensures safe operation by isolating Arduino from high motor currents while enabling full robot movement.

Arduino Obstacle Avoiding Course

    The Arduino UNO is the microcontroller board used as the brain of the project. It is based on the ATmega328P chip and has 14 digital input/output pins, 6 analog inputs, a USB connection, and a power jack. It processes the code uploaded through the Arduino IDE and controls all the connected components like the motor driver and ultrasonic sensor. In this project, Arduino continuously receives distance data from the ultrasonic sensor and makes decisions to move the robot forward, stop, or change direction. Its simplicity, open-source nature, and community support make it ideal for beginners in robotics projects.
