Obstacle Avoiding Robot Car using Arduino Kit

The Obstacle Avoiding Robot Car Arduino Kit is a DIY robotics kit designed to build an autonomous robot that can detect obstacles and change direction automatically. It uses an ultrasonic sensor (HC-SR04), Arduino Uno, and a motor driver module to control DC motors. This is one of the most popular beginner robotics projects for learning automation, sensors, and embedded systems.

• Operating Voltage: 7V–12V (recommended 12V battery pack)
• Control Board: Arduino UNO (ATmega328P)
• Sensor: HC-SR04 Ultrasonic Distance Sensor
• Detection Range: 2 cm – 400 cm
• Motor Driver: L298N dual H-bridge
• Motor Type: DC BO Gear Motors (100–300 RPM typical)
• Control Logic: Obstacle detection + directional response
• Movement: Forward, backward, left, right, stop
• Power Supply: Battery powered (portable robot)
