Upload the Code:

Connect the Arduino to your computer and upload the code using the Arduino IDE.
Power the Robot:

Power the robot with the battery pack or a suitable power source.
Test Your Robot:

Place obstacles in front of the robot and observe how it navigates to avoid collisions.
This simple project demonstrates the basics of robotics, sensor integration, and autonomous behavior. You can expand on this project by adding more sensors, improving obstacle avoidance algorithms, and even implementing remote control via Bluetooth or Wi-Fi.

Project: Arduino Obstacle-Avoiding Robot

Components Needed:

Arduino board (e.g., Arduino Uno)
Ultrasonic sensor (HC-SR04)
Motor driver module (L298N)
Two DC motors
Chassis and wheels
Battery pack (6xAA batteries) or a rechargeable battery pack
Jumper wires
Breadboard (optional)
Instructions:

Assemble the Robot:

Assemble the chassis, attach the DC motors to the wheels, and mount the wheels to the chassis.
Connect the motor driver module to the motors and the Arduino.
Connect the Ultrasonic Sensor:

Connect the VCC and GND pins of the ultrasonic sensor to the Arduino's 5V and GND pins, respectively.
Connect the Echo and Trig pins of the sensor to any two digital pins on the Arduino (e.g., D2 and D3).
Programming:

Write the Arduino code for the obstacle-avoiding behavior. This code will use the ultrasonic sensor to detect obstacles and make the robot move forward, backward, left, or right to avoid collisions.
