Obstacle Avoiding Robot Car 

Overview:

The Obstacle Avoiding Robot Car is an autonomous robotic system that can detect obstacles and avoid them automatically. The system is built using an Arduino microcontroller and an ultrasonic sensor.
When the robot detects an object in front of it, it automatically changes direction to prevent collision. This project demonstrates basic robotics, sensor integration, and automation concepts.

Key Features:

1. Automatically detects and avoids obstacles.

2. Uses ultrasonic sensor for distance measurement.

3. Autonomous movement without human control.

4. Simple and cost-effective Arduino-based design.

5. Can move forward, backward, left, and right.

Main Components:

1. Arduino Uno – main controller.

2. Ultrasonic Sensor (HC-SR04) – detects distance and obstacles.

3. Motor Driver (L298N) – controls motors.

4. DC Motors – for movement.

5. Servo Motor (Optional) – rotates sensor for wider detection.

6. Battery / Power Supply

7. Chassis & Wheels

IoT Integration (Optional Upgrade):

IoT Features:

•  Mobile app control (Forward, Backward, Left, Right)

• Auto Mode and Manual Mode switching

• Automatic stop when obstacle is detected (even during manual control)

• Remote control from anywhere via internet

Additional Components for IoT:

1. ESP8266 (NodeMCU) – WiFi connectivity

2. Mobile App (Blynk / Custom App) – user interface

3. WiFi Network – for communication

IoT Platforms Used:

1. Blynk Apps and Website.

Applications:

1. Autonomous robots

2. Smart vehicle systems

3. Robotics learning projects

4. Industrial automation
