DC MOTOR SPEED CONTROLLER USING ULTRASONIC SENSOR

In the year 2021 around 4 lakh accidents road accidents were reported in India. Most of the accidents these days have occurred due to negligence of drivers unable to control speed and bashing into obstacles causing fatal injuries. Sometimes there are sudden interferences while driving and lack of in-time reflexes to them causes accidents, we have inculcated this issue in our project. Our aim is to prevent accidents by controlling the speed of DC motors in case of any obstacles according to distance. In this paper, we would like to give an introduction followed by a brief idea of the components used, a flowchart of the system then it’s hardware, software methodology, testing, and conclusion. The main concepts used for this device are Ultrasonic sensors to detect obstacles and PWM to vary the speed of the DC motor using the L298N motor driver. We believe our project can help reduce accidents and provide a safe traveling environment for everyone.
