Here are the step-by-step Video instructions to build an Arduino-based Obstacle Avoidance Robot using an ultrasonic sensor and DC motors with an L298N motor driver.

Components Required:

1. Arduino Uno (or Nano)

2. Ultrasonic Sensor (HC-SR04)

3. L298N Motor Driver Module

4. 2x DC Motors with Wheels

5. Chassis (robot frame)

6. Caster wheel (optional but recommended)

7. Jumper wires

8. Battery (e.g., 9V or 12V Li-ion pack)

9. Breadboard (optional)
