Self driving car using Arduino.               Self driving robot is an intelligent device which can automatically sense the obstacle in front of it and avoid them by turning itself in another direction. This design allows the robot to navigate in an unknown environment by avoiding collisions, which is a primary requirement for any autonomous mobile robot. The application of obstacle Avoiding robot is not limited and it is used in most of the military organization now which help carry out many risky jobs that can not be done by any soldiers.              This project we are going to use Arduino microcontroller, Ultrasonic sensor, Servo motor, gear motor, wheel, motor driver and battery. Here an Arduino id used to control the robot and an Ultrasonic sensor is used to sense the obstacle in the path and calculate the distance between the robot and obstacle and change the direction to continue moving. Component required. 1.       Arduino Uno. 2.       HC-SR04 Ultrasonic
