  INTRODUCTION An autonomous car,also known as a self-driving car or driverless car, is a vehicle that is capable of sensing its environment and navigating without human input. This is achieved through a combination of sensors, cameras, radar, and software that work together to interpret the car's surroundings and make decisions about how to navigate. Autonomous cars have the potential to revolutionize transportation by improving safety, reducing traffic congestion, and increasing accessibility for people who are unable to drive. However, there are still many technical and regulatory challenges that must be overcome before they become a common sight on our roads.

  D C M oto rs • Amotor is an electrical machine which converts electrical energy into mechanical energy. • The principle of working of DC Motor is that “whenever a current caring conductor is placed in a magnetic field, it experiences a mechanical force “. • Electrical motors are everywhere around us. Almost all the electro-mechanical movements we see around us uses them. • Additional sensors and electronics control the DC motors.

  WORKING  The Arduinowe used here is connected here with sensors and motors both servo and dc Motors .  The sensor receives a signal whenever an obstacle is detected .This signal is then sent as a feedback to servo motors to change its angle, While the dc motors are stopped.  And then it’s checked that the path is clear. If it is then the DC Motors are turned on.  The obstacle detection check occurs repeatedly to avoid collision,this is possible due to the sophisticated algorithm used in it.

  Future Scope This Projectis all about Self Driving Car using Arduino which avoids obstacles when it encounters. In future this project can be enhance by connecting a camera so that the user can see the detected obstacle on his screen by sitting at just one place and we can also implement GPS module to make this car self sufficient.
