Our company AR Tech is going to build a car which prevents collisions and this all can be done by installing an ultrasonic sensor on the car. This car will be operated with the help of Arduino and the sensors will identify the obstacles and change direction accordingly. Whenever the car senses an obstacle, the ultrasonic sensors will send the signal to Arduino and the wheels of the car will stop. The servo motor will help in changing the direction of the car. Hence, it prevents accidents.
