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 robot chassis is the structural frame that holds all the components together. Usually made of acrylic, plastic, or metal, it provides the base for mounting motors, wheels, Arduino, motor driver, sensor, and battery holder. The chassis ensures stability and organizes all parts for neat assembly. It also comes with pre-drilled holes to fix components easily without soldering or drilling. In this project, the chassis supports the weight of the robot and enables smooth movement. A sturdy chassis ensures the robot remains balanced while moving, turning, or avoiding obstacles, making it an essential mechanical component.
